My boyfriend and I have been dating for almost three months, but we've never really talked about our past relationships with each other. I feel that as his girlfriend, I have a right to know his past history, especially his sexual history. For me, it is a big deal if one of my boyfriend's isn't a virgin. I want to find out who he's been with, how far he's gone, etc. How do I do this without feeling like I'm prying into his personal life?
