I'm never quite sure when I lost my virginity. What necessarily counts as losing it? When I was 15, with my then boyfriend, we tried to do anal but realized spit isn't great lube when you're new to it. So there wasn't much sex going on. I'd have to say the first time I really had full on sex was when I was 18. I don't regret it, no. I don't see virginity as some holy thing that needs to be preserved. I would date a virgin. I don't care really. I might prefer they have some sexual experience but eh.
