Do i seem like a Sl**?

some grls seem to think im a slut, cuz they think im the sort of grl that will sleep w/ every guy i date. Thats so not tru. if im going out w/ a guy we have to be dating for over 6 months n order to get some. and they say im a slut w/ the way i dress..... i wear regular clothes. for example jean pants or shorts and a top. I think the only think this cuz some of the guys they like usually end up liking me, but majority of the time i dont like them back or i dont date guys that my friends like. so y r they calling me a SL**????
