it's because our bodies send out this type of hormone and it makes us UBER sleepy.
i forgot what that hormone was called.. oxyto.. sumthing
or possibly the answer is that when guys do ejaculate it uses a lot of blood out of the rest of their body to fill all of the nervs in the penis and the sudden blood rush after ejaculation back to their heart and head it sometimes causes them pass out!! its totally normal! as long as he is not out for hours...lol
Well, not so much, president101. Not only do nerves not "fill" with blood (rather, blood vessels that expand are basically how erection happens), when women or men -- who BOTH experience the exact same kind of genital vasocongestion, so given the clitoris has far more nerves than the penis, your theory would have women out for a day -- orgasm, BOTH can feel sleepy, tired and the like.
It's in no way unique to men: more times than not, we simply see men experience it more often because so many women complete sexual activity without reaching orgasm, and/or women feeling less comfortable rolling over and falling asleep because some feel it's rude, etc.
Fakeshawon was on to something: there are a handful of hormones that come into play with both arousal and orgasm, like oxytocin, dopamine and endorphis, which are basically natural opiates. To boot, plenty of people are physically active enough during sex that that adds to a feeling of tiredness. And on top of THAT a simple feeling of comfort, emotional satisfaction, and the snuggly-buggliness of intimacy with a partner also contribute.
And just for the record: no one should normally be literally passing out or blacking out after sex. That isn't normal.
