I hear sometimes of male prostitutes who service other men. I can’t say I know anything about those whose clients are female. Some maybe intend to have female clients, but it goes another way, like Jeff on American Dad (since it seems to me that most clients are men, whether they’re looking for a female or male prostitute):
“After we ran out of money, Jeff suggested that we prostitute ourselves. At first, Jeff was saying he was only going to do women, but then… that wasn’t working out. So, long short story, Jeff’s on butt rest, and we moved to the desert.” xD
