The last time I've heard anyone giving a crap about virginity publicly was at a frat party. Somehow it came up, the virgin was a guy and the other guys responded with "that's cool, man."
The last time I witnessed someone get made fun of for being a virgin was in high school, but in high school, you get made fun of for having tied shoes or untied shoes, brown or black or blond hair or red hair, preppy clothes or gothy clothes, bad grades or good grades. Basically, everything is fair game anyway.
Its no shock that there are virgins and non-virgins of all ages and I think most people know this and don't seem to care either way. Its mostly magazine/media editors that write trashy sex articles that pretend to care about someone's virginity.
People are more worried about what other people think of their own virgin status to bother caring about the virgin status of others. I don't think I was ever made fun of either way, but then again, no one cared enough to ask whether or not I was a virgin and I didn't think it was appropriate to advertise.
If someone actually gets made fun of for being a virgin often, it makes me wonder how and why they feel compelled to tell people in the first place. That may have more to do with it than being a virgin.
