Is This a Bad Idea???

I posted on the other pregnancy forum but I wanted to post here to get some advice from other teens. Even though i'm 19 and about head out of teendom I think that I still can say what I want to on here... :)

my bf of three years and I are battling the long distance relationships while we are both at college. It really sucks. When we do see eachother we get intimate, we're both virgins and having sex hasn't really ever come up. We've been raised in christian homes and taught that it was right to wait unitl marriage to have sex. However, we do fool around, and by that I mean dry humping, masturbating eachother and grinding against eachother. Everytime that we do this we are wearing at least underwear, and me normally shorts.

Can pregnancy be caused by this? I'm not sure if he's ever actually comed, but there is precum since i've felt it before. Basically, I just want to know if anyone has gotten pregnant by doing this and how many of you girls do? Sometimes I feel like i'm the only one out of a lot of my friends who's still the virgin and I just was wondering.

Sorry this is so long and i've given you all my life story, but I feel like you all have so much more knowledge about this then I do. Gosh I feel so ignorant!
