there is nothing wrong with you. your just a classy girl that enjoys dancing but doesnt want to get too close. just because you go to a club it doesnt mean you have to act like a slut. a lot of my friends say that they like going to clubs, but they dont like it when guys get too close. if you are there to dance and enjoy yourself, then there is nothing wrong with just dancing with a guy, and when he gets too close to tell him to stop.
a lot of people think that if you go to clubs you have to dirty dance with every single girl you meet, thats stupid. last saturday night i was walking past a group of girls, and one of them grabbed my arse, and started rubbing herself on me, i was like wtf? get off. thats why i think alot of poeple dont like clubbing these days, its too sex orientated.
if your not comfortable, then dont be ashamed of it, that just means that your a classy girl.
