You need a BS detector.....& sex is a good one......anyone who wants to have sex before having a long relationship with a person & really getting to know them (& in my belief, sex ONLY a part of marriage). I can guarantee, keeping sex for marriage definitely keeps the low lifes away. If you hold to those values, it sifts out only those who are interested in you for having sex & it makes you feel much better about yourself because you aren't loosing out on any possibilities by holding out, you are only loosing out on the BS that the losers have to offer.
