I'm 19 and a female and I have been seeing my boyfriend for over a year and a half now. We haven't had sex yet due to either my not being ready in the beginning (I'm a virgin and so is he) or just having no place secure to actually do it since his mom is always home and my mom is home quite frequently. He is now 21 and is away at school a lot of the time as well but the past couple of months I have been asking whether we should have sex once he gets his own place. He previously had a dorm room with an obnoxious roommate who doesn't understand the concept of privacy. But since he has come home for the summer he is avoiding the topic. I even try to bring it up when we would make out or touch but he would just change the topic and recently it has begun to upset me. We have never had much of a sex life we saw each other about once every 3 weeks or so but he would drive two hours just to see me and we texted or skyped almost everyday apart. I know he's not cheating on me but he still won't talk about it. What should I do?
