I am not arguing Herero versus bisexual. I am illustrating the variations in human sexuality, including gay, lesbian and bisexual.
As I had mentioned before, human sexuality is about choice. Everything is possible if you choose. It's not going to choose you. A performer can go in any direction he or she is willing to go. They can start as gay, or bisexual. But if they get bored, they can go into heterosexual porn. Of course, they have to work it out with their agents.
Porn performers make enough to pay the bills like rent and the car and etc. Most use the money made to either go to college or go into other things outside of porn because they can't do it forever. A few have went into legitimate mainstream acting or other legitimate ventures.
