My boyfriend has a problem with sex, I know him very well and I know he's not just being a guy. He likes to play around a lot but he's very iffy about me touching him I don't know how to help this or what to do... he did have a really terrible experience when he was younger but he's had long term relationships and he has slept with other women but only 2. He wants to have sex we've tried it once but he got too nervous about it and pulled away I don't know how to handle this situation?

I'm a 17 year old girl and have been dating this guy for a year and a half. I love him and know he loves me. For about the past six months I've been giving him handjobs. We started out slowly. (Through his pants, though his boxers, and then of course through nothing.) Well, recently he has been trying to convince me to let him fingering me. I told him "no" and he was pretty respectful of that. Each time we do something though, he asks for it. When I say no, he keeps saying 'okay, I'll wait for you" When he kept asking, I said wait till I'm in college and we'll see. Then, he said okay again. Once he asked me why I wasn't ready and I said because I was scared. When I couldn't explain why I was scared he got a little frustrated. He still keeps asking me for fingering and as I say no, he says "It's okay I'll wait for you." I just want to know though, how I can get him to stop asking, it kind of feels like he is pressuring me. I've tried to find a reason for my fears, but I can't place my finger on it other than I'm not ready. (It doesn't help that an old of crush of his- who is both of our friend- is telling him about how her boyfriend gave her first orgasm through fingering.)
