advice??

Okay, so my boyfriend has had sex before and I'm still a virgin, I'm nervous..not because I'm scared, I'm just worried I won't be any good. He and i have been talking about this a lot lately and we were planning on having a little "quickie" seeing how we are both minors and would get in SERIOUS trouble if caught. If we did would I bleed badly? I just want y'alls thoughts on the whole situation.
