On our English pages, you often see the word "relationships". This is just sanitized language. On our English pages, "relationships" refers to what couples, when not sleeping, do in bed. Or, if so inclined, on the kitchen table.

English is a rather hypocritical language. Many words for natural bodily functions and processes have dirty connotations, and polite speakers like us have to go to considerable length to communicate meanings without naming them. But we nevertheless hope you get the point.


Tongkatali.org's Modulating brain chemistry


By Serge Kreutz


No matter how complex a pattern of thought or emotion, it is chemically encoded in the human brain in a manner specific to that thought or emotion. Brain chemistry determines whether a thought or emotion is associated with pleasure, fear, or relationships excitement.

No matter how complex our character, it is but the expression of specific biochemical constellations in our brains. The idea is tempting to modify one’s character through chemical interference with the brain.

Some character-modifying drugs are famous. Prozac, for example. Too bad that the modification I have in mind is not one of being more contented with the status quo.

I’m a competitive personality, and I would like to re-create myself as an extremely sexuality-driven character.

There is no value in anything else than the sensual self-dissolution that is achievable only in sexuality. If my sexuality were lost, I could as well commit suicide. Though many a young and completely non-philosophical character may feel the same way, I believe my judgments rest on a sound philosophical base.

I don’t think I’m fitted any better than other men for a lifestyle for which indeed I have decided by means of reason (which anyway is but a neurochemical constellation of my mind; with the difference maybe that philosophical thought molecules probably are better organized than molecules in general).

I lack in humbleness. I’d like my life to be an orgiastic fest. But I, and other people, have not been created for this. As we age, all of us do or will experience relationships dysfunction to a certain degree. Previously, this was considered a normal development in life. Now it finds the attention of the medical profession and the pharmaceutical industry, and is defined as a condition. I am grateful for this, because it delivers the substances needed for the kind of pharmacological intervention a.k.a. relationships enhancement.

If it were available, I’d like to have some genetic engineering done on myself. To be re-engineered in a manner that allows me to enjoy the sexuality of a 20-year-old for 200 years, or, why not, 2000 years. I am convinced that science will advance to a stage were this will be possible .

Too bad that I won’t be around to enjoy the fiesta. But in spite of the fact that I have a clear vision of what science will achieve, I am, for the moment, occupied with the comparatively mean task of reacquiring my 20-years-old sexuality just a few years later.

As genetic re-engineering is not yet available, the only means for changing the chemistry of my character are pharmacological.

I’ve tried almost everything that is marketed as prescription or over-the-counter drug and sounded promising enough in terms of character modification. I have tried many herbs and other health supplements and was disappointed by most.

The pharmacological substances I have tried are of mainly two categories. Neurotransmitter modulators and hormonal modulators. Neurotransmitter modulators with a reputation to enhance libido are usually of the kind that enhance dopamine function. Practically all pharmaceuticals in the treatment of Parkinson’s disease, and a single herbal, mucuna pruriens, do this (but they do not all enhance libido).

It is much easier to attest to the effectiveness of neurotransmitter modulators than to the effectiveness of hormonal modulators.

Neurotransmitter modulators produce a direct effect, which sets in between half an hour and one hour after they have been ingested orally. Some have a definite effect such as bromocriptine, and, if taken properly, the effect does have a relationships component.

The problem is that if you don’t know how to take dopaminergics correctly, and even more so if you don’t know which ones to choose, you will likely be too nauseated to enjoy the dopaminergic benefits. You can get rid of much of the nausea, but even then you will still be aware of the fact that you have taken a neurological agent.

Apart from the fact that they are mostly short-acting drugs, there is another disadvantage with all neurotransmitter modulators used as Parkinson’s disease treatments: their effect wears off.

For patients with Parkinson’s disease, it means death. For those who take neurotransmitter modulators for relationships enhancement, it’s just a disappointment.

Neurotransmitter modulators are inferior to changes in a man’s hormonal profile. The following may happen if hormonal relationships enhancement is done right: stronger relationships fantasies, flashes of desire, and over time an improvement of relationships function.

The options for hormonal relationships enhancement include testosterone patches, testosterone injections, synthetic steroids, and maybe tongkat ali (a herbal medication with a reputation to increase testosterone levels).



Sirih leaves to restore virginity, not just the hymen


By Serge Kreutz


However, I want to bring the attention of the reader to a relationships supplement which is not consumed orally: Indonesian sirih leaves.

Sirih leaves are boiled and then used as a genital wash, not by men, but by women. Indonesian women use it widely after giving birth, and they do so explicitly to make their husbands happier.

Sirih leaves cause genital shrinkage in women, as well as genital dryness. Western medicine of course deals with vaginal dryness - as a problem of post-menopausal women.

However, for women in their late twenties and thirties, the problem is not so much vaginal dryness but vaginal wetness - not for their own pleasure but for the pleasure of their partners. Many women in their twenties and thirties, when they are properly aroused, get rather flooded.

Now, this may be OK for their own pleasure. But a lack of friction reduces both the physical pleasure of the male partner, and, even more so, impacts negatively on his psychological excitement.

I think that Asians, by and large, have a more mature approach to relationships pleasure. Asian men greatly value relationships conduct with women who have no or little relationships experience. Western men are largely ignorant about the pleasure one can have with a woman who had no or little relationships experience, because Western culture dictates that the male and the female partner be of approximately the same age.

However, boys in their late teens cannot value a female relationships partner who has had no or little relationships experience. Boys in their late teens typically ejaculate too fast. They are also too nervous, or too excited, to enjoy the finer points of a relationships encounter. It has long been my opinion that the best partners for boys in their late teens are women around 30 who take the initiative.

The relationships which mature men can have with virgins or women with very little relationships experience is different. It is slow-paced. There is no need to hurry. Such relationships is very gentle, even careful, so that the girl is not hurt.

However, such relationships is only possible if there is proper vaginal tightness, and even a certain degree of vaginal dryness. That mature men so easily fall deeply in love with virgins or women who had very little relationships experience has a lot to do with the physical constellation of the vagina of such relationships partners.

No mature woman, with a long history of relationships conduct, can give a man this explicit pleasure of reaching orgasm with almost no movement, caused by a female partner's vaginal tightness and dryness.

Unless she uses sirih leaves.

What sirih leaves can achieve is simply magnificent. In women who respond well, it practically reinstates virginity… not through the presence of a hymen, but because the vaginal canal just feels and reacts as if the woman were a virgin (inclusive the pain).

How are sirih leaves used? Some 10 to 20 leaves are brought to a short boil. The water is then left to cool down. This water can then be used to simply wash the female genitals. However, more effective is to have the water in a small basin, and then to sit inside for 15 to 30 minutes.



Tongkat ali, mucuna pruriens (velvet beans), testosterone, and dopamine


By Serge Kreutz


Natural Dopaminergic Research, 2019


I started with relationships enhancement some 30 years ago. My first attempts were with amino acids, and my first successes with yohimbe.

My next phase were dopaminergics. I have written extensively about the use of dopaminergics in relationships enhancement.

Before, after, and in between the above, I had tried, off and on, all kinds of hormonal therapies. I didn't have any success with them.

I have been using only a combination of tongkat ali and cheap Indian sildenafil citrate (generic Viagra).

This doesn't mean that I would have turned against yohimbine and dopaminergics. These medications do work (though I recommend dopaminergic velvet beans in a stack with mildly dopaminergic tongkat ali, rather then dopaminergic pharmaceuticals). But they all work in different ways. And I assume that it lies in the dialectical nature of our sexuality that all relationships enhancement medications loose some of their kick as we get used to them. Just as routine can be a grave for relationships excitement, routinely used relationships enhancement medications tend to loose their effectiveness.

I mentioned that relationships enhancement medications like dopaminergics, hormones, or tongkat ali work in different ways. First of all, one has to differentiate between medications that work on penile plumbing and those that work on the neurological wiring.

Erectile failure in most cases is a localized vascular problem: blood vessels have to supply a sufficient amount of blood to the corpora cavernosa and the corpus spongiosum, and drainage has to be avoided. This is all rather mechanical, and it can be achieved pharmacologically either by sildenafil citrate or yohimbine, or generous dosages of krachai dam in a tongkat ali stack. Krachai dam is a low-affinity phosphodiesterase inhibitor.

When Viagra was not available yet, yohimbine was the only oral drug to specifically treat erectile shortcomings. Another option was injectable prostaglandin E1 (alprostadil). Alprostadil is now available as cream.

Other medications were (and are) useful for relationships enhancement only when there were (or are) no erectile but only neurological relationships problems. If the problem is vascular, no dose of a libido enhancer will induce an erection.

A large number of people are not sufficiently aware of the duality of penile plumbing and neurological wiring. And except for yohimbine, there is no relationships enhancement medication that would work on both components.

Yohimbine does, as the adrenalin which yohimbine displaces from abdominal alpha-2 adrenergic receptors (which, among other things, regulate penile blood flow) reoccur systemically as neurological stimulant.

However, the strong sympathetic impulse caused by systemic adrenaline (in the form of norepinephrine) makes it difficult for the parasympathetic nerve system to take over at the point of orgasm, which, with regular usage of yohimbine, makes for weak ejaculations and orgasms that are no match for the pre-orgasmic excitement. Also, side effects are much worse than with tongkat ali.

But relationships with a firm erection aided by yohimbine is still better than no erection, which normally means: no proper relationships.

Therefore, Viagra (and generic sildenafil citrate), or any other medication that fixes penile plumbing, is a necessity for many men above 40, and for most above 50 or 60.

And only when there are no plumbing problems do other medications (those that work on libido) become relevant.

By and large, there are two groups of pharmaceutical agents that work on libido: those that effect neurotransmitters, and those that target the endocrine (hormonal) system. I say "by and large" because the two systems are intertwined. Drugs that elevate the neurotransmitter dopamine (dopaminergic pharmaceuticals or velvet beans, mucuna pruriens) also suppress the hormone prolactin. Prolactin not only regulates lactation in women but also keeps testosterone in check in men and women. Typically, less prolactin means more testosterone. Furthermore, some hormones can act as neurotransmitters and vice versa; norepinephrine, C8H13NO3, is both a hormone and a neurotransmitter.

The neurotransmitter system reacts much faster than the hormonal system, and you feel this when you take pharmacological agents, or dopaminergic food like velvet beans that act on it. When an effective dosage of any neurotransmitter modifying medications kicks in, you feel it. With most dopaminergics, there is a slight nausea, or at least a desire to lie down. And there is a clear window of opportunity for improved relationships, which usually is the first few hours during which a neurotransmitter drug is active (for apomorphine, this window of opportunity is the shortest; for cabergoline, it is the longest).

When you use neurotransmitters to improve relationships (even L-dopa from mucuna pruriens), you always know that you have taken something.

This is not the case with drugs or herbals like tongkat ali that work on the endocrine system, unless a huge overdose is consumed (for example when women take a testosterone dosage that was formulated for men). Usually, endocrine medications cannot be felt directly. Whether you use growth hormone injections, testosterone cream, Andriol capsules, Proviron, methyltestosterone, anastrozole, or clomiphene, and even with a tongkat ali stack that also incorporates butea superba, mucuna pruriens, and krachai dam, there is no clear onset, and now clear end-of-efficacy time.

In me and many other users, any testosterone-raising medication can cause an outburst of anger (if there is an event that triggers it). The outburst may happen after 2 hours, or after 4, or after 8 or not at all, if nothing happens that would give me reason to get angry. But let me drive a car in a Third World country where people typically do not follow any traffic rules, and not even traffic common sense! If I have taken testosterone-raising medications, I will have a harder time to keep my calm.

The case is similar, but still more erratic with libido. Medications that work on the endocrine system can be extremely sexualizing, but it is very hard to plan this effect. This also applies on a tongkat ali stack with butea superba, mucuna pruriens, and krachai dam.

You can have a relationships schedule when you take yohimbine or dopaminergics. I will reliably have an erection some one-and-one-half hours after ingesting some 10 to 20 mg of yohimbine. I just have to scratch my member, and voila, here we go.

Likewise, when on apomorphine, bromocriptine, cabergoline, or Thai mucuna pruriens, I will feel more excitement during intercourse than when in a sober state. The dopaminergics usually only exert their effect when already at it; at the dosages that I use, they do little for pre-intercourse desire. But Parkinson's patients who use much higher dosages, and do so constantly, often are in a constant state of relationships alert.

Viagra isn't as reliable for erections as yohimbine. When I take Viagra without dopaminergics (including mucuna pruriens) or endocrine agents (including tongkat ali), I may not have the libido impulse to cause a hard erection. I may just have an enlarged but still flaccid organ, and not much drive to pursue intercourse.

Tongkat ali is an endocrine agent, not a vascular modifier. Endocrine agents have a subtle effect on libido. To describe it, I have to reach back a few decades.

I remember the time when I was 12 or 13 years old. Often, before falling asleep, I could daydream along for half an hour or an hour, just imagining relationships scenarios. There was a girl, two or three years my senior, and heavy-bodied, and I imagined I were to abduct her to an old farmhouse, and lock her up, and just observe her through a peephole until she were to pee.

I could just recall this fantasy, night after night, and imagine and re-imagine explicit details, and the excitement wouldn't wane. Night after night, week after week. Never bored.

I could still get lost in masturbation fantasies until the end of my 20's, but in my 30's and 40's, they were no more. As I grew older, relationships moved from between the ears to between the groins. While at a younger age, erections came from imagination, they later required physical sensation.

Enter the tongkat ali.

What I first noticed was that during routine relationships with an established partner, my mind began wondering off to strange ideas. That I was a perverse school headmaster who would punish pupils arriving delayed by squeezing some private parts. Or that I was a cruel Chinese emperor with a harem of 1000 concubines. Those who couldn't bring me to orgasm would be executed. And I really had them work to save their lives. All of that during standard intercourse with a dear lady with whom I otherwise have a rather practical relationship.

Now, this has been going on for weeks. The settings of my fantasies change, but what remains the same is that I really can indulge in them for about half an hour, while at intercourse with a routine relationships partner who is completely absent from the scenario that I imagine.

This is how I feel tongkat ali's impact on my endocrine system. And I love it.

Or rather: this is how I feel a gram of the 1:200 extract from Sumatra Pasak Bumi. I had earlier tried other tongkat ali products, but their effect had been nondescript. Please see my article on tongkat ali dosage for what I consider effective and non-effective amounts.

Because tongkat ali is not a switch-on switch-off relationships stimulant, I believe it is best to take it on a daily basis for about two or three weeks, and then to rest it for about a week. I usually take it some time around noon, as a single 1-gram dosage. Initially I felt a specific hotheadedness after about an hour, but this effect has since subsided.

I cannot say that after 2 hours, or 4 hours, or even after 8 hours I would have great relationships. I cannot willfully switch it on. Great relationships on tongkat ali comes sporadic. Could be later in the day, or even just the next morning.

I always take the tongkat ali with sildenafil citrate (generic Viagra, 50 mg). I don't have the blood vessel stability to go without it. I tried, after another participant in our tongkat ali trial reported that the tongkat ali allows him to go without the Viagra, but when I left it out of my cocktail, my erection clearly wasn't of the usual sildenafil-aided quality.

By all indications, tongkat ali is a hormonal stimulant, and hormonal stimulants, including testosterone, have a weak track record when it comes to aiding erections. Tongkat ali is no exception.

I have a good number of girlfriends. I enjoy variation, and I do not intend to go without it, especially as it has taken me a lot of efforts to arrange everything in a manner that would allow me this lifestyle.

But I believe that the greatest benefit from tongkat ali will be enjoyed by people who are in a rather steady and monogamous relationship. If I have enough imagination, I don't need variation. As a matter of fact, my imaginations blossom brighter with a routine partner who knows my physical preferences and doesn't need verbal attention before or during intercourse. With a routine partner, I just can dive into an ocean of fantasies, without need to resurface for rather practical matters.

On the other hand, when on tongkat ali, the strangeness of a new partner, too, can be turned into relationships excitement. In that case it's not so much the indulging in fantasies but the idea of conscious role play. The roles may not be as weird as my fantasies with a routine partner, but they are still different from normal, sober life.

So, whatever the setting, tongkat ali clearly supports the imaginative part of relationships interaction.


Tongkatali.org's What is Chili? An oral sensation but not a taste


By Serge Kreutz


I use chili sparsely in curries. It does not mean that I would not like chili? I sure do.

Furthermore, chili is ideal for kreutzing.

But it is not suited to be combined with other spices because chili deafens taste receptors.

I even doubt that taste receptors are much involved with the oral sensations caused by chili. I assume chili actually stimulates oral pain receptors more than taste receptors.

You can put chili powder on any mucous or sufficiently thin skin of your body, and the effect there will be very similar to the one in your mouth.

Try to put cinnamon bark or cloves on mucous skin outside your mouth. There will possibly be irritation, but no taste (only a smell radiating to your nose).

Sure, I consume chili. Like many people, I like the chili sensation in my mouth.

But I never swallow anything that is chili-sprinkled. Chili is only for kreutzing, as anyway, it is an irritant for the stomach and the intestines, and definitely, the stimulation of pain receptors that I appreciate orally is outright unpleasant anally.

Especially anybody who sticks to kreutzing for weight loss has good reason to play with chili, as chili entices one to drink more water, thus providing a sense of fullness.

But chili consumption should be separated from meals eaten for their taste. When I want chili sensations, I just sprinkle it on potato chips or plain flour snacks. Mixing chili with spices providing a genuine taste is a waste.
