I don't believe in virginity. It's a stupid concept to begin with, and we pay way too much attention to it. I had a first breath, a first ice cream cone, a first step, a first job, a first airline flight, a first kiss, a first mosquito bite, a first piano lesson. None of the tens of thousands of other "first times" gets its very own word.
Anyway, since I don't believe in virginity, I don't really understand the question. However, I can substitute sex in general, and say we should have it whenever we feel like having it, in the safest possible circumstances, with the clear consent of all participants, and ideally with a foundation of trust between all comers. (So to speak.)
