Male Physiology Question - How Do Men Cum?

[Safe_Bet]

My daughters are of an age where they are becoming curious about the other sex. So last night during dinner, dessert actually, while putting whipped cream on my pumpkin pie, I was asked if men really "squirt" when they cum. I told them, "yeah, I think so. At least in the movies!". They then asked "How" and I was stumped.

So my question is (and using my pumpkin pie as an example): is it like the whipped cream where you press a valve and the stuff sprays out cuz its under pressure, or is it like when my pie goes down my throat and esophagus in a series of rhythmic contractions or is it like it was bad pie and it's a violent "projectile vomit like" spasm?

Inquiring minds want to know! (and yeah, I know I can FGI, but I really don't want to know more about the male reproductive system than necessary! )

I would refer to it as rhythmic contractions. Sometimes it can be more spasmic and explosive when the guy is really pumping it out.

Is there a husband/father of the daughters with whom you might experiment/experience? I'm sure he wouldn't mind being your "test subject".

Did you take note of the pretty rainbow colors on my Av, BTW???

And no, we can't ask "dad" cuz his name is Mr. Mystery Sperm Donor and his dick was a syringe!

A syringe might be a close example only like the other poster said, it would be a series of rhythmic pulses instead of one long squirt. The longer it has been since the last ejaculation the stronger the squirt.

My apologies. Nope, didn't note the AV. That said, I'm sure you might find a willing volunteer who can demonstrate/show if only for purely scientific purposes. He might even be willing to do everything himself (masturbate) if given proper incentive. Just a thought.

In terms of the male orgasm/cum, it still falls into the rhythmic contractions as to how the ejaculate spews forth. Hope that helps. Good luck with your daughters!

I always thought it was pretty similar to a repeated sneeze (but then, penises remind me of noses, sniffing around hopefully for a hole to play in, lol.) But technically the prostate gland collects up fluid until it says OK I'm full enough, and then that gland dumps its contents into the urethra and the muscles in the penis push it out in pulses. This kind of pulsing muscle movement is used in lots of places in the body (pie going down your throat is one, pie going through your intestine is another, menstrual cramps pushing blood out is a third and labor cramps pushing a baby out is a fourth.) Only the first shot or two of cum travels any distance, the rest are more like, umm... when you push the pump on a hand soap bottle. And after 6 or 8 there's some left-over pulsing but no noticeable amount is coming out.

That's about as accurate as I could describe it. Stronger spurts in younger men, slower in old ones.

Wiki has it down pretty accurately...

When a man has achieved a sufficient level of stimulation, ejaculation begins. At that point, under the control of the sympathetic nervous system, semen containing sperm is produced (emission).[3] The semen is ejected through the urethra with rhythmic contractions.[4] These rhythmic contractions are part of the male orgasm. They are generated by the bulbospongiosus muscle under the control of a spinal reflex at the level of the spinal nerves S2-4 via the pudendal nerve. The typical male orgasm lasts several seconds.

After the start of orgasm, pulses of semen begin to flow from the urethra, reach a peak discharge and then diminish in flow. The typical orgasm consists of 10 to 15 contractions, although the man is unlikely to be consciously aware of that many. Once the first contraction has taken place, ejaculation will continue to completion as an involuntary process. At this stage, ejaculation cannot be stopped. The rate of contractions gradually slows during the orgasm. Initial contractions occur at an average interval of 0.6 seconds with an increasing increment of 0.1 seconds per contraction. Contractions of most men proceed at regular rhythmic intervals for the duration of the orgasm. Many men also experience additional irregular contractions at the conclusion of the orgasm.[5]

Ejaculation begins during the first or second contraction of orgasm. For most men the first spurt occurs during the second contraction. The first or second spurt is typically the largest and can contain 40 percent or more of the total ejaculate volume. After this peak the flow of each pulse diminishes. When the flow ends, the muscle contractions of the orgasm continue with no additional semen discharge. A small sample study of seven men showed an average of 7 spurts of semen (range between 5 and 10) followed by an average of 10 more contractions with no semen expelled (range between 5 and 23). This study also found a high correlation between number of spurts of semen and total ejaculate volume, i.e., larger semen volumes resulted from additional pulses of semen rather than larger individual spurts.[6]

Alfred Kinsey measured the distance of ejaculation, in "some hundred" of men. In three-quarters of men, the semen exuded from the penis, "In other males the semen may be propelled from a matter of some inches to a foot or two, or even as far as five or six (rarely eight) feet".[7] Masters and Johnson report ejaculation distance to be not greater than 30–60 cm.[8]

Amy,
If I understand it right, there are two systems in place to expel semen. There's the "contractions" system ( a bit like arterial swelling and contractions) which gets the semen out of the gonads and up in towards the urethra;
And
There's the more "muscular" system for expelling the semen which can act as an accelerator to propel semen to the outside.

But the pump for cream is a good analogy, even it is is a different physics.

BTW. Tell me about the rainbow rose; I' didn't know it meant anything.

Well, your daughters could ask the syringe but it likely wouldn't have much to say as it was only a substitute dick

Resisting bad jokes isn't good for you; you'll do yourself an injury.

I'll agree with Wikipedia - it's rhythmic squeezing that normally results in a couple of violent squirts first off that have some pressure to them (I have actually came in my own eye before, which was interesting), followed by a bit of pulsing that doesn't accomplish as much.

While I'd never thought to compare it to bad pie spasming, that's probably a fairly close physiological movement. And now an unfortunate mental connection.

At least it wasn't Mr. Turkey Baster.

Yeah, it's pretty much a squirt. Young dudes go for distance; older dudes for technique. The little wigglers find their way home either way.

The wiki article gives a nice (if bewildering) mechanical description of the physiology of the male orgasm but tells you nothing what it feels like subjectively, especially the intense and often obliterating pleasure of a good, hard, ejaculation.

I'm sure it's a bit different for each man, but the main distinguishing feature of the male orgasm is the explosive expulsion of semen. I think most men would agree that sexual arousal is experienced as a kind of tension or pressure that steadily increases, starting in the penis, and then spreading to the lower belly and genital region. The prostate can get involved. For me, at least, the tension spreads to my thighs and ass, my arms and shoulders, and even my scalp. All the major muscle groups are involved, and the entire body feels extremely tense and swollen and on the verge of explosion. The important thing here is that the pressure and tension are no longer just genital, but deeply somatic. The need for release can be so intense that we shake or tremble.

The orgasm itself is a rather diffuse and all-encompassing feeling of intense pleasure and release, the release caused by the ejaculations. The feeling is of ejecting all this anguish and tension and pressure into your lover. The semen is ejected in discrete "shots" and propelled by the peristaltic squeezing of the inner plumbing (it's complicated in there) and the penis itself. The prostate's involved too but the man might not be aware of this because he's already tightening his ass in a reflexive attempt to thrust more deeply, and it's the ass-tightening that puts pressure on the prostate. But have someone put a finger in your ass when you ejaculate and you'll certainly feel the contractions that squeeze the prostate

The actual mechanism of ejaculation is the reflexive peristaltic contractions of the urethra. It's the same motion we use to squeeze toothpaste from a tube or, in reverse, when we eject the contents of our stomach when we vomit. The first ejaculation is the strongest, and a young man lying on his back can easily shoot a wad of semen 4-5 feet into the air in his first ejaculation. The second ejaculation is usually not as strong, and the third weaker still. Despite what the Wiki article says, I personally am aware of maybe 3-4 hard ejaculations, and the remaining semen feels like it's pouring out in a stream.

I should say, by way of citing differences, that although I've heard men talk about feeling pressure in their balls when aroused, and being aware of the their testicles involvement in ejaculation, I never have. They're there, and they apparently do what they're supposed to do, but I'm never aware of any tingling or throbbing or sensation of them being emptied like I've see in other reports. Since testicles aren't directly involved in the mechanism of ejaculation, I have to wonder whether those aren't just psychogenic effects.

Now I'm hungry.

Based on some of the stories I have read here, it's more like opening the valve on a fire hydrant and allowing the gravitational pressure to push a torrent of fluid through a fire hose for anywhere from 5-30 minutes.

 

[lance gt]

From a different perspective that has been given here, a man's penis works on hydralics through blood flow. When stimulated, it becomes engorged and erect, thereby increasing the sensitivity of the tissues. There are several key areas of sensitivity, along with numerous methods of stimulation, orally, digitally or vibratory and of course, through intercourse. When the penis has been stimulated to a certain point, signals from the brain set the process of ejaculation into effect. In most cases, it can't be stopped once started, unless control is practiced, or stopped from reaching the apex of stimulation, usually done during a FemDom session or similar.
The prostate gland is like a Gspot for men and when stimulated from the anal passage, can increase the intensity of the orgasm.

Am I the only person who is suspicious of Amy's enquiry on behalf of her daughters. Is her question in the same category as, "My friend has a problem."

A subterfuge to cloak her own unrealized, sub-conscious interest?

But then, I might just be a suspicious old so and so.

Yeah, because discussions of male reproductive mechanics is SO sexy, right? Especially when it's described as projectile vomiting followed by the dry heaves? Oh, baby is THAT ever a turn on, huh?

Seeing as that's how YOUR mind apparently works, I bet a discussion of menstruation or full vs. partial mastectomies would be a major "subconscious" turn on for your pervy ass!

I'm sure the use of a squirting dildo would suffice her interest in dicks per se, but questions by her daughters wouldn't be out of the question. I've seen enough guys ask about women's bodies and how they work, so the reverse isn't hard to believe.
I will commend her on trying to explain a subject she herself finds distasteful and do it without prejudice.

There's no gravitational pressure.

Well Amy, you started the topic of male reproductive mechanics, and you take first place for your reference to vomiting too. So both are the product of your mind.

I do admit to knowing a bit about menstruation because I worked as an AI man in my summer vacations many years ago as a student .A knowledge of female anatomy, ovulation, menstruation was essential.

On your last subject, Mastectomies: my knowledge of radical surgery is secondary but all too clear. Incidentally I went to the cricket in Sydney yesterday because it was Jane McGrath day. If you google Jane McGrath you will understand what I mean.

Good point. Comedy is dangerous but not worth an aneurysm.

And now I must do some research then report back to Amy.
