Why do man wake up with there penis on hard?

Question

Men only not you dum a-s--s whore .

Answer 1

Most men are deeply affected by stored subliminal images of flighty, semiliterate, wet-crotched hoochies like you. When these images emerge during sleep, usually expressed as erotic dreams, then the condition known as a hard on, or in some cultures as morning wood, occurs. This condition is best facilitated in healthy males whose levels of testosterone and other body chemicals are supportive of sleeptime erections.

Answer 2

When a man is sleeping most of the blood will flow back to the center of the body. This casues him to have several erectons during sleep. I beleive the one in the morning is natures way of keeping us from peeing all over ourselves. Man it is hard to pee with a stiffy.

Answer 3

it is quite often caused by pressure in the blatter that has built up over night (8 hours without peeing). The full blatter will put pressure on the prostate (some people call it "the male g-spot). This can cause arousal/erection.
