Body odour, general cheapness and the fact that in their society women are lesser so they rest all females the same
For AA.. I ha e heard, dick size, aggressive behaviour and low tips as excuses, in all honesty, most of it is either stereotypes or blatant prejudices that people are afraid to admit to.
I have had RT providers I’ve known a long time tell me they would fuck me if I was not so big , and I’ve also had FS providers say take your time as Chinese an not so big or so long, I’ve had some who will ride the shit out of it and want more,
I personally think it comes down to personal preferences a bit of past experiences and also pussy preservation it this is for FS spots, if it’s a RT spot it’s because you are either nasty, dirty, smelly or cheap....or a combination of all
