<human>: Hi /r/relationships, first post, throwaway. I've never really been on this subreddit before, so please excuse if I do something wrong.

My girlfriend and I have been dating since high school. I was raised in a very relaxed religious household, but she was raised in a "church every sunday", Southern Baptist type household. She Tithes, volunteers every Sunday, the whole nine yards. I myself believe in God but I don't really adhere to a particular faith. I've got my own personal relationship with God and I don't think he requires anything of me other than being a good person, which I try my best to be. 

But anyway, when we turned 18 we began exploring sex. She didn't want to lose her virginity, so, like teenagers, we have kinda done 'other stuff' which is basically no PIV. Not trying to be crass but basically oral and hands. I know, very teenagery.

She is telling me now, after over 2 years of being sexually active that she feels too guilty about it and doesn't want to do any form of sexual activity until marriage. And we love each other like crazy and we plan on marrying each other, its just that we are both at Uni and don't have well paying stable jobs to start up a life and get married. I completely support her in her faith. I go to church with her and even volunteer sometimes, despite not really being into her particular sect.

I feel a bunch of different things. I would never try to force her or say she owes me sex. But I don't understand why now is when this has to change. I feel unloved and like she doesn't find me attractive anymore. And I know that its because she feels her devotion to God, but I don't believe that at all. It isn't like we had this issue from the beginning. She never felt particularly guilty before, and I love my blowjobs and she loves her fingering and oral. 

Its all kinda fast and Im a little out of it and really tired when writing this, so please excuse me not typing well.

Summarize the given text in a few sentences.
<bot>: My girlfriend feels guilty about being sexual with me because she is christian, and said we can't do stuff anymore. What do I do? How should I feel?
