Should i blow him...?

Wow. I was 15 a while ago...but I remember it well and I don't ever remember wondering about these kinds of things. My guess is your going to do whatever you feel like no matter what anyone tells you on this thing. My advice...can you make out with him instead? Does it have to go to the next level? I hope not. I remember the girls who got the reputation for going there and I'm guessing you don't want to be one of them. If you are dead set on doing something with him there's nothing wrong with a hot make out session...I still enjoy them! Whatever you do, be careful and don't get talked into anything you'll regret later.
