Can breaking a girl's hymen and getting blood on your penis be dangerous in any way?

Relax, but....: If you're going to have sexual intercourse, please go to the library, book store or internet and learn a little about it. It'll save you a lot of grief and keep you out of trouble. The blood isn't a problem (and it won't get "inside" your penis) but it could also mean you're being exposed to HIV and/or stds. Haven't you ever heard about "protection"?
