I wonder if any of you guys know WHY you wake up with an erection most of the time. whee When you sleep, your testosterone levels rise, so that means you're more prone to an erection, thats why most of the time you wake up with an erection, even if you did'nt have an erotic dream.
On another note, morning wood is very fun when i get to be with my fiance. twisted That's not necessarily true.
It is possible for testosterone levels to rise whilst asleep, but testosterone is not what causes erections... Women have erections too.
[And women also have testosterone, but not high enough quantities to back up your theory]
During REM [Rapid eye movement] sleep, NPT [nocturnal penile tumescence] occurs, and it happens 3 to five times each night. This is due to increased blood flow during REM sleep.
So basically, when you're sleeping, your blood flows more freely. Guys get 3-5 erections per night... morning wood just happens to be when you wake up during one of them.
