Wow. Just WOW. The previous poster is so wrong that I dont even know what to say. polopunk, I suggest you go give head to a 12 gauge.
What you are referring to is called "Nocturnal penile tumescence". It happens to pretty much every man, usually a few times a night.
Wikipedia says "The cause of NPT is not known certainly. Bancroft (2005) hypothesizes that the noradrenergic neurons of the locus ceruleus are inhibitory to penile erection, and that the cessation of their discharge that occurs during REM sleep may allow testosterone-related excitatory actions to manifest as NPT."
Basically, when you are awake, there are certain chemicals that inhibit erections unless you are aroused, but when you sleep those chemicals go away, and it can manifest itself as an erection.

guys cannot pee and have an erection at the same time, so when guys get older instead of wetting there bed, they get an erection.
its really simple
