some of your hormone levels peak a few hours before your regular waking time. it is the prerogative of life to reproduce, and this trick has been working for a long time…

it a signal u need to go pee, dude, simple as that. or, there’s a chick next to you who is takingadvantage of u :-)

the reason for morning wood is good reason to wake up my girlfriend.

It’s has something to do with the flow of blood while your sleeping. Your blood slows down while sleeping and when your body starts to wake your blood rushes through your body or something like that. Also what buster said.

Morning Wood, or Nocturnal Penile Tumescence, is basically an evolutionary attempt at keeping men “dry” while they’re asleep, so as to keep the rest undisturbed…ladies, you probably don’t know this, but it goes down after you pee; aka “Nocturnal Penile Tumescence.”
