Hi,
I have worked with lots of male escorts, and the truth of the matter is you will need to determine if you are a giver or a receiver. Sorry but that is grim reality. In the male escorting world it is mostly men who are closet, bi-curious, or in denial about their sexuality, you will also get couples, but very rarely women on their own. And if you do get a woman who calls you up, take some re-enforcements, Viagra is one recommendation, seriously, because she will make you work for every penny she pays you! Also you don't want your erection to be dependent on desire. If you get my meaning.
Good luck Violette
