I've already heard that during orgasm, the penile muscles contract, which produces that amazing feeling. But it doesn't make much sense because I contract many other muscles all the time, and they don't feel like that (imagine your whole body orgasming). Also, what makes the in and out/up and down motion physically crucial to reaching orgasm? It just doesn't make sense to me, and I've always wondered what scientifically goes on during the male orgasm.
And one more thing: What makes an orgasm so relaxing? It relieves a TON of tension...but how?

MrFlux

It's all about the endorphins.

what he said
we dont get full body orgasms

Technically, the male ejaculation and orgasm are two entirely different entitys, but just happen together so often that we think of them as one big maglavin.

During the male orgasm, the main neuro-chemicals released are called (as stated above) endorphins. They are THE pleasure chemicals, you get them released in response to extremes of pleasure or pain, spicey foods, excitment, mood altering drugs and, as we all know, sex.

When the endorphins are released into the brain by the hypothalamus (i believe it's that, but i'll look it up) your suddenly forced into a state of pleasure, or if in pain, less pain. At orgasm, the release of endorphins is so high, at the exact moment of orgasm your consious mind monentarily shuts down, if just for a nano-second.
Try and think about something next time you have an apointment with mr.righty, and you'll see what i mean.


The up/down in/out motion that brings a man to ejaculate is simply the by product of thousands of years of sex. The main aim of sex is fertilisation of the female to produce offspring. Since at a base level sex involves the male phalus moving in an out of the female, our brains have been programmed to understand that in this scenario, we need to release sperm to make babies.
Genetic programming at a basic level.


Now, as pleasure chemicals are released during arousal and sexual activity, it is possible to build up the levels to a state in which every nerve in your body becomes hyper-stimulated. When these nerves are stimulated, they send off a message to the brain, which just releases more endorphins, and so on and so forth.
The human brain cannot be kept in this state for very long before it has to dump all the chemicals out it's relays and press re-set, not doing so would result in a rather nasty short circuit.
An orgasm at this time will accomplish this transmitter dump for you, as firstly the release of further endorphins due to orgasm will inhibit any major release after that, and the elated high you will be in will stop pretty much any activity until your body can calm down and figure out where it is and where it left the packet of ciggarettes.
If this type of activity can be kept on for long enough (i.e. going right to orgasm and stopping short over and over again) the high that the orgasm release of endorphins will give you is, shall we say, large?
It is entirely possible to have a full body orgasm if you are a man, it's just something that takes a little time to learn how to do.


Edit: please excuse the rambling, it's early and i havn't had breakfast. Me and my toast will look for some more science to back that all up later.

Its not impossible to have a full body orgasm for a man, like the above poster stated. I know from personal experience that it can happen, a lot of what keeps a man from doing it is the state of mind they are in when they orgasm, if you are preoccuipied with other things you will never get into the right state of mind for it to happen. You pretty much have to focus 100% on it. And In addition it's not going to happen with a quicky either there needs to be a slow build up, then you can have your legs spasm and body contract all over the place aswell.

Thank you for your awesome responses! So the function of sex has to do with how the brain handles it, and the feeling of an orgasm is dependant on body chemicals (endorphins).

Now, another question: Can endorphins become addictive? 'Cause I know I'm addicted to sex, even though I can and do restrain myself.

Yes, you can become "addicted" to endorphins, you can literally become adicted to sex, but it usually(not always, but usually) takes larger doses of endorphines than your body can produce naturaly. One such thing is cocaine, it gives you a big kick in either endorphine levels or sensors, but it has pretty much the same effect. That is one of the reasons cocaine(and drugs derived from it) are the most addictive substances on the planet, cause their the only thing that makes you feel better than sex, it's supposedly(I haven't taken it, so I don't know for sure) like having one huge, long, intense orgasm.

Endorphines are good, but in moderation.

Then why are coke users so angry all the time?

stevie667

Coke is a mood hightener, if you feel good, you'll feel even better, if you feel bad, you'll kill someone.
Theres also the fact that coke is highly addictive, and anger is a classic symptom of withdrawl.

As for cocain being better than sex, nah, not a chance. I don't much like cocaine, it's too shortlived and expensive, and unless you plan to take a few hundred quid worth, doesn't give you a huge endorphin release.

But, back to the subject at hand, you can become addicted to the high of endorphins, but thats rare.
Getting addicted to sex i figure is just one of things that happens, so don't complain...

Dunno if it's just me but i usually have a feeling of euphoria after orgasm for about 20 minutes(it's slowly decreasing the whole time but i can still feel it). That and it's nice to have that pressure relased from my balls.
