Some women have had bad experiences with men of certain a ethnicity- and that can be all it takes to put them outside of their comfort zone...
For that, and feeling like it is personal, I am sorry.
I try not to judge anyone by their ethnicity or complexion.
I don't even ask what race a guy is, because really it does not bother me, however,
I too have noticed a trend of ladies putting race on their booking forms.
I thought it a bit odd, but to each their own.
I have heard there is someone for everybody in the hobby!
Just like some gals may be too fat, thin, old, young, too dark, or too light to really "do it for you"- fear not,
there's still a lady out there for you!
Try not to take it personal or to get discouraged!
