@Cthulhu , I think there isn't an inherent problem with being a virgin because all of us had to start there anyway.
You need to know, however, that girls are definitely more attracted and turned on by a sexually experienced man than to one that's not, because they know he will provide them with a great sexual experience. This is the essence of
sexual prizing--letting the girl know that you are knowledgeable about sex and therefore promising great sex once the two of you seal the deal (girls get whack sexual experiences from chody men all the time--cut them some slack).
So, the best thing is to, well, make sure they don't find out, as that doesn't your endeavors (if your goal is to sleep with these girls). You don't have to lie about it, but you don't have to discuss it either.
Do you think they'd make fun of me?
I also think you are worried about the wrong thing. Your mind should be set on how to get those girls attracted to you and get them to bed, not whether they will laugh at you or not.
