Sex work is a time honored tradition for transsexuals. Prostitution, escort, porn, what have you. It pays the bills. It might degrade the community, but a lot of people don't have a choice. You know... there might actually be more cispeople in the sex industry than trans, though!
When he was on Howard Stern he said that he loved his pussy and would never get rid of it, it's a part of him. Probably not the same response that most trans people would give, but he's comfortable, he's got limited options, and he makes a lot of money with it I'm sure. His life.
