Most girls I have ever talked to bout this says its cause most of the guys are aggressive, pimps, or too big for them. I don't care what race you are either way. I see ALL races. The girls who have a NBA policy have had a bad experience of some sort that a little more screening or any screening at all, could of been avoided.
I get asked all the time by clients why some have policy and some dont. I can just answer the question with what I've been told. Anyone can be aggressive, pushy, hung, whatever. 95% of these bad seeds can be avoided with good screening. Just saying!!
