Sometimes when my girlfriend plays around/ teases me for any more than like 3-5 minutes of like really soft gentle touch I get extremely erect to the point where its painful and it feels like my penis is trying to escape the skin its confined to.

I am 19 and have 7.5" normally but this bumps it to around 7.7-8". I am circumcised, if that means much. Is there a way to fix this or at least ease the pain, it is overwhelmed when I am pleased but it is not enjoyable before.
