Internalized homophobia? =/

Hello. My name is Jasmine and I have a few questions.

I have a girlfriend of 6 months and counting, however the relationship is one that has gone through a great deal fo turbulence in such a short space of time. We broke up for about three months, discovered it couldn't be like that and have recently gotten back together.

However the problems are, of course, stil there.

I've been reletively comfortable with my sexuality since I came out about four years ago; I wish I could say the same for my girlfriend.

I'm certainly not the type to push for anything sexually, but she has like extreme problems with intimacy. I know for a fact that a lot of the time she'll be feeling a bit ashamed and possibly even disgusted at her own sexuality. Yet she can't seem to let me go? When I say problems with intimacy.. she'll have to be in a really steller mood to hold hands or show any sort of affection, and kissing/etc is a rarity. When she's had something to drink and we're alone sometimes the problem will just disolve completely, but again, it's a rarity.

Over time it has started to hurt really quite a lot, and I start to wonder what on earth I'm supposed to do because I know I don't want to loose her again. 

I'm so confused by it all, and this is just about the only thing I can't talk to her about in great detail because I don't think she even knows herself.

Barrghh. =[

Anyone got any experience/suggestions? I'm really open to anything anyone has to say.
