<human>: I have been dating this girl for about 6 months. (Me 24, her 21) She has been wonderful, except she wants to wait til marriage to have sex. She is a Christian, of course, and I am agnostic and her first boyfriend. However, I have slowly started to find hard to not have sex, as I have always done that in previous relationships. She happens to be very flirtatious, likes to tease, and we do engage in other things (oral and such), but she will stop me, literally, at a point just before sex. It's gotten to a point where I sometimes get aggravated when she gets flirty. The thought of waiting years to have sex doesn't appeal to me, but I personally find it shallow to break up with someone because of sex. We've talked about it, and she says that she wishes we could sleep together, but her convictions for God's will and risk of that strong emotional attachment that comes from sleeping with someone prematurely stop her. I am not sure of anyone else who might have gone through this before, especially those in an "inter-faith" relationship, I suppose. I am not religious, and I personally find attachment to religious dogma and "God's will" silly (although I am respectful to her), but I also don't want her to sacrifice her closest beliefs for my desires. 
I'm really at a crossroads right now, and am looking for advice from people with some experience in this situation. I would really appreciate honest feedback.
