Be honest. Nobody can see your specific vote, so you have no incentive to lie. I'm not a virgin, but I lost my virginity very late in life. I was 21. (I did fool around for a few years before that. Saw a few boobies, got a few blowjobs, but does that really count? I don't think so.) And I've only had sex with two people in my entire life. BE HONEST.
