for me, if i was the guy, it would matter to me if my gf is a virgin or not I need to know her past and who she hooked up with before I guess it's very important to open up about that in a relationship to establish that trust and disregard the "I think he/she is hiding something from me" Feeling.... It's okay to talk about that issue to strengthen the relationship. But guys never bring up that topic to your crush or to some girl you're courting... It's a big NO-NO a huge turn off
