I agree with others on disclosing that info upfront. Not to make the escort comfortable, but to avoid an awkward situation for yourself. Or to avoid wasting your valuable time. And no you can't assume just cause their ad doesn't say they have racial hangups that they don't have them. Now if they say they are open to all types then yeah it's a safer bet. But most guys that have racial hangups probably are NOT going to put it in their ad. In my case I once had a client not tell me his race. I got there and he had this nervous look on his face that could have been avoided by just telling me beforehand. The whole time he waited for me to arrive he had to wonder... Of course I was okay with his race and we had a great time together. But not everyone is open, so save yourself the trouble.
