PM erections....what causes them?
 

All males have erections when they are young. Sometimes when they
are not wanted . I remember having a super hard on once when I was in
wood shop and I was embarressed as others noticed my condition. As
you get older the day time erections are less and less and then it's some-
times hard to get hard,but there is the "PM" or night erections; an automatic
thing where you wake up with a stiffie. Does anyone know what is the
main reason for this? I know during the night ,you probably have not used
the bath room and a certain amount of pressure is built up....but is this it?
Maybe a Doctor could answer my question but I never think about this when
i'm in his office. :)

I don't know why, but I'm glad it happens. :D

Morning sex is the best alarm clock ever.

Hey, love your erections. I love mine. When you're old and you can't get them anymore except with the help of some damn pill, you'll reminisce back to the "good 'ol days."

Post Mortem erections? No no no thats not an erection thats rigor mortis!

Asta!! :thumbsup:

LMAO at K-Wise's wise ass comment.

Someone told me it's a sign of a good circulatory system but don't quote me.

What causes PM erections? Excess blood fills the spongy tissue in your penis.

Why do you ask?

when i am get tired, i ALWAYS get an erections doesnt matter what time of day it is....if i get tired it happens!! tho some are worse then others hehe

Love it man. Enjoy it while you still got it.

What causes PM erections? Me :)

My lil theory is that just being relaxed opens the capillaries (or whatever the word is) so you get partially erect, but in doing so part of you notices that you are now partially erect, so you become more erect until fully so.

I dont wake up with morning woods much these days and I'm only 20. Maybe once or twice a week.

This phenomenon is NOT conducive to safe sex :hmm: pity..

I get hard if i lay down to sleep - even for naps... :crazy:

Morning Wood?
 

I know that is what makes them but I am talking about why
we get them while we are asleep? "Morning Wood" and I think
HALX must have the best answer so far. He said it is caused
by a full or near full bladder pressing against the prostrate
gland. :thumbsup:
