Re: my Penis ain't sleep well?
If you believe there is a problem such as high blood pressure, you should see a doctor to make sure you do not have any medical problems. I understand what you mean about problems in P.E. I remember some guys being made fun of in my classes for the same reason.
Do you wear tight underwear? If you wear some tight or tighter underwear, that may be able to keep your penis closer to your body. Some guys also wear their penis up and off to an angle instead of down. If you do it properly, the penis will just compress into your abdomen and it should not be visible.
Finally, some guys have really tight circumcisions which causes the penis to always point out instead of down when it is flaccid. As everything fills in during puberty, this problem can become worse. If this is the case for you, you may need to explain the situation to someone if they question it.
I hope that helps.
