I've spoken to male porn stars who referred to themselves as try-sexual, as in they'll try anything for the money.
I don't have a penis so no clue how they work it, but I don't think gay for pay makes them bisexual, unless they like cock in their spare time too. And there are plenty of guys out there like that too.
A porn director once told me that he tells guys who want to get into porn that if they can get erect and walk naked through a crowd of people and still keep it up, then they are suitable to do porn. I think it is more of a sex drive thing than a preference, when they are that serious about being a manwhore.
but gay for pay is real, its like saying are guys who have had prison sex bisexual too? nah, they just need a little "affection."
