Why only in U.S?? I think it's difficult to remain a 25+year old virgin even in Nepal... I'm not generalising, but until a girl elopes(poila as we say) with the very first guy she is attracted to, it may be difficult for her to remain a virgin hehe... And if a girl could have her say then I guess she would choose to taste and throw a stinky tempting bone than make it the "tilhari" and drag it forever.... Ready for all the probable attacks Mokshyaa ;-
