I'll try to make this short, but here it goes:

I've been going out with my current girlfriend for two months now, so it hasn't been too long, just feels like a long time now, since we see eachother almost everyday. She's the kind of girl who's never had a serious relationship, and this is her first with me. The longest its lasted for her before was about a month. She's 17, I'm going to be 20 soon. She's never even made out yet, but I never make a big deal out of it, I just tease her about it and it's no issue. She's actually pretty open about sex and we talk about it regularly and it doesn't seem to bother her much at all.

However.. about a week ago, she had something to tell me. She told me she was "affraid of how much she liked me" and that she had never felt this strong in a relationship before. She's really in touch with her emotions, and when we first went out she had a lot of difficulty expressing herself with words, but I told her I understood that she was shy and it was all new to her.

But now after almost two months, we're somewhat comfortable enough with eachother, we know eachother better as time goes and we discover new things we like or may not like. Except ofcourse that we still haven't made out. We talk about it, and how it should work.. but there's something I don't understand.

She slowly pushes me away. When we kiss, it's fine. But whenever I try to kiss her more than once in succession, she pushes or slowly pulls away and lets go. For example..3 nights ago, we were on the couch and we started fooling around and kissing eachother more than usual, but as soon as she sensed we would enter that "makeout" zone, she made motion for me to stop. I suggested we forget about it and try some other time.

I ask her sometimes what is wrong and If I'm doing something that she doesn't like, but she says she does like the way I do it. Last night I tried kissing her neck before I came back home, but she told me to stop. I asked her what was wrong and if she didn't like it anymore, but she replied with "no, it's because I love it so much". so huh??? I can't go much farther at this point, I'm still trying to connect this behaviour with what she said above; "I'm affraid of how much I like you". She told me herself it had something to do with it, but I can't really put the pieces together. Maybe it's something about me she's not telling me or doesn't have the heart to say, but sometimes when I feel her hands put pressure on my chest for me to back away, it kind of hurts emotionally.

Can anybody gimme some insight on this? Is this common? I understand she's completely innexperienced, but I never try to force anything on her. Sometimes I think it's love I feel for this girl and hurting her like that..I could never. I don't care *GASP*!!!! about the sex, I only want her to feel comfortable I guess.
