On Male Orgasm and Prostate Play 2

by Jason Stotts

On the original “On Male Orgasm and Prostate Play,” a reader asked the following question:

This is a really good article. I appreciate that it focuses alot on the anatomy and phisiological aspect of the orgasm, and not just “stroke his cock fast with 2 hands” like alot of male orgasm articles. I think it’s very important to understand the anatomy of a male in order to create a good orgasm.

I would be interested to find out about specificly what goes on inside the male right before and while he orgasms. How long does it take for the sperm to get from the testicals to the opening of the urethra once arousal begins? Does it graduately move from the testicals at different stages of arousal? or does the sperm shoot from the testicals to the urethra opening right at the moment he “peaks” ? also.. when is the most effective time to stimulate the prostate? before during or at the late “almost there” stages of arousal? and.. can you stimulate it adiquitely from the prenium?

Since I didn’t think anyone would actually see my comment on that essay, I’m reposting my answer below.


First, thank you. I also think that understanding anatomy really helps one to understand what’s going on and how to maximize whatever it is that you’re doing.

Unfortunately, I don’t have any information about exactly when semen is produced. I can, however, give you some information that will help you understand how it works. The testes produce sperm constantly and store it up so that there is always some ready (this is why they’re housed outside the body, to keep the sperm relatively cooler). However, the sperm actually make up a very small percent of what we know as ejaculate. Roughly 2/3 of ejaculate is produced in the seminal vesicles and the other roughly 1/3 is produced by the prostate itself. While there are other minor glands involved, these three are the most important. If you think about the location of these organs, you’ll see that nearly all of the ejaculate is produced either in or right around the prostate (where it enters the urethra) and the travel distance is negligible. The prostate actually swells and holds the ejaculate which comes out at the moment of orgasm (through muscular contraction). Although I don’t know for sure, I would imagine as a man gets excited, the sperm makes its way up into the prostate to be ready.

In terms of stimulating the prostate, you can begin this at any stage of arousal. Although, if a man is new to prostate stimulation, you would want him to be aroused before you start so that he will be more receptive to it. While it is most certainly possible to stimulate the prostate through the perineum, it’s not a very direct way to stimulate it. I know that none of the above diagrams show it, but you’ll be trying to stimulate the prostate through a number of different pelvic floor muscles (like the pubococcygeal) and through the base of the penis itself (remember the penis actually goes into the body a little ways where it is anchored, it is not just the external part you can see. The problem with this kind of external stimulation is that it is not very direct and you won’t be able to feel his prostate well at all.  You’ll also be pushing his muscles into his prostate, not touching his prostate itself.

The ideal way to stimulate the prostate is through the anus. Now, many men won’t be open to this right away and will likely balk due to concerns about being gay or hygiene. The first concern is absolutely unfounded and the second can be mediated by a little soap in the shower and a good diet. Either way, there is usually no fecal matter stored in the rectum itself (the area right inside the anal sphincter).

In terms of when to stimulate the prostate, it’s completely up to you and your partner. I would try different ways to see what works for him. If you’re doing it internally, you’ll actually be able to feel his prostate swell as he gets close to orgasm and then you’ll be able to feel it contract when he actually does orgasm. I personally think right before he orgasms would be a really bad time to start internal stimulation, since that will take a second to get set up. If you’re doing external stimulation, it would probably be fine though.

If you do decide you want to work up to internal prostate stimulation, here’s a couple of ideas that might help. First, start slowly! Begin by just slowly rubbing the outside of his anus for a couple of sessions with no penetration. Second, use lube! Use more than you think you need and make sure to reapply. I suggest using latex gloves to make it less messy and to protect his anus from your nails. Third, even after you start penetrating his anus with a finger, you should still go slowly and maybe wait a couple of times before you actually stimulate his prostate so that he has a chance to get used to anal stimulation (which most people really like, if they can get past some mental barriers). If you’re going to go this route, and I recommend you do for prostate stimulation, get Dr. Jack Morin’s Anal Pleasure and Health.

New Discoveries about Penis Birth Defects

by Jason Stotts

The BBC is reporting that scientists have isolated a gene that plays a role in the malformation of the penis during pregnancy and fetal development.  The malformation is called hypospadias and it is when the opening of the urethra is not on the head of the penis in it’s usual spot, but lower on the penile shaft or even at the base of the penis.

Researchers from King’s College London, and Radboud University Njimegen Medical Centre in the Netherlands joined forces to carry out a large scale genome study.

This compared the genetic code of hundreds of boys, with and without the condition, to uncover genetic mutations which appeared more commonly in those with hypospadias.

They found that boys with a mutated version of the DGKK gene were 2.5 times more likely to be born with hypospadias.

This is fascinating research and hopefully it will lead to the ability to stop hypospadias from forming in the future.

In case you haven’t heard about it yet, you should definitely check out this news article on FoxNews about the computer virus stuxnet, which has all but crippled Iran’s nuclear program.

Simply put, Stuxnet is an incredibly advanced, undetectable computer worm that took years to construct and was designed to jump from computer to computer until it found the specific, protected control system that it aimed to destroy: Iran’s nuclear enrichment program.

I think whoever designed and implemented stuxnet should get a Nobel Peace Prize for hampering the crazy and destructive Iran.  It really is a work of art and can be credited with delaying the inevitable war with Iran.

UN: You Can Now Kill Gays

by Jason Stotts

In a move that further goes to show why the UN should be abolished, the UN has removed language from its position on unjustified killings that made killing due to sexual orientation illicit. Now, it is no longer an unjustified killing to kill someone for their sexual orientation.

UNITED NATIONS (Reuters) – Arab and African nations succeeded Tuesday in getting a U.N. General Assembly panel to delete from a resolution condemning unjustified executions a specific reference to killings due to sexual orientation[…]

But this year, Morocco and Mali introduced an amendment on behalf of African and Islamic nations that called for deleting the words “sexual orientation” and replacing them with “discriminatory reasons on any basis.” [Emphasis added, though probably not needed.]

Islamic nations rejoice!  You can now kill the gays without worrying about the UN trying to stop you.  The US, of course, was afraid to say anything against radical and murderous Islam:

The U.S. delegation voted against the deletion but abstained from the vote on the final resolution. Diplomats said the U.S. delegation also voiced disappointment at the decision to remove the reference to sexual orientation.

Even though we didn’t vote against the measure, I’m glad we “voiced our disappointment.”

When will religionists of all kinds of irrationality, christian, muslim, and all the other crazies, realize that there is nothing aberrant or unnatural about homosexuality?
