Ok i'm a fifteen year old guy. and i am used to sleeping on my stomach. But as some of you may know, guys get hard while they sleep (morning wood, etc). so i was wondering, does that damage the penis? cause it already goes backwards (towards my stomach if i'm laying down) when it is erect. so is that what causes it or is it normal?
Don't worry how you sleep. It probably makes you better (or at least more exciting) than your peers.
just dont try to make love to the bed,hehehehe .-respect the blankets.-
heheh
