So I've started dating this 19 year old girl and she's a virgin. She's catholic. I think that she is afraid of sex to some degree. We've slept together once and we got halfway there and she was trembling with anxiety. Despite this, I still want to see her again. I'm naturally drawn to challenges like this. However I feel that when we do finally have sex that she's going to cry. It's hard to explain why I think so, but I just have this gut feeling that she's going to break down afterwards. What do I do in this situation? I have no idea how to handle this part.

It's probably worth mentioning that the last time I saw her I tried initiating a few times and she scurried away from me on the bed. After doing this three times she gave me this look that said "please don't hurt me" like she was genuinely afraid I was going to rape her........I'm starting to think this isn't really my problem, but instead it's something she's gotta figure out on her own.
