I told him I wanted to have sex but I think I changed my mind...

I'm going to be a junior college and I started hanging out with this guy and I really like him, blah blah... We started to hang out towards the end of the spring semester. We've only kissed a couple times but the last time we saw each other before we flew home for the summer we almost had sex. I am a virgin and wanted to save myself until marriage but in the moment, I really wanted to have sex with him. Anyways, we kept talking over summer and got to know a little bit more about each other. He told me that even though it was unfortunate that we started to hang out so close to summer and won't see each other for three months, he enjoyed the time I spent with him and that he is looking forward to hanging out again when we get back. We are not dating but he has said that he likes me, misses me and he is a real gentlemen in person. He would never do anything that I would not let him do. Here is the problem...We snap chat so we get to see each other a little bit. But, those snap chats turned into sexy snaps. Pretty much (I'm a little embarrassed to say but) we pretty much have "Skype sex" or sex on snap chat and tell each other what we would do to each other. It gets pretty detailed and we've done it plenty of times. The thing is I want to have sex with him but sometimes I want to save my virginity for marriage. I guess my question is How do I take sex off of the table after I pretty much told him exactly how I was gonna do it with him? Or should I just give into my desire and just do it and see what happens? I don't know what to do because I like him but don't want to make things awkward between us. I also have a fear of getting pregnant and losing my athletic scholarship. Since I am a virgin I am not on birth control because there was never a need. Should I get on it? If I do, I might use it as an excuse to have sex with him even if I choose that I shouldn't. Any thoughts...?

I think you shouldn't have sex with him that's risking your future and you don't want to be telling your husband your not a Virgin. Just tell the guy you don't want to have sex. & he should respect that if he really does care for you.
