We're both 19, sophomores in college. Met in mid-october and have been together since then. She was a virgin. First day back from break (early January) we had sex for the first time and have been regularly since then, every single time she sleeps over (3-4 times a week? sometimes more), usually once or twice at night and once or twice in the morning, with a few afternoons sprinkled around. We do missionary, her legs up on my shoulders, cowgirl, and variations of those (her leaning back with her on top, legs every which way, etc etc). But she won't do it from behind, or any variation (reverse cowgirl, spooning, doggie etc). When we apart (school breaks, during class sometimes, etc) we have full on sex texting. I'm talking 30 minute conversations that usually end in something along the lines of her saying "I was quivering at the dinner table and had to go to the bathroom, run the water and finish myself off". Where I'm going with this is that she's kind of a nympho recently ex-virgin. She doesn't have huge boobs (but I love em ) but she does have a great butt and legs, which I remind her of about 25 times a day, coupled with the fact that she knows that i am a huge legs/butt guy. Yet she still isn't comfortable with it. We openly talk about sex and today I was saying "I really want to try it from behind, I think it'd be really good for you" and she just said "it's going to take a while before I get to that point"... Any suggestions? I don't want to do it for myself (she's so tight and wet every position is unbelievable for me) but I think it'd be a lot better for her and I'd do a better job of consistently hitting her spot.
