I tend to be nonplussed about gay for pay/G4P porn actors because it is all fantasy- I will probably never encounter many porn actors (I've actually met 2 - so yeah, weird), and unless I am interested in having sex with them (which for even ones Im attracted to…yeah, no), this wouldn't be an issue.
This post made me think about strippers a lot. I live in a city that doesn't have male strip clubs, but there are some not too far away, and there's something I like about the attitude of the strip club which is why I go. If a stripper was hitting on me and then said he isn't gay or bi, I'd probably not be interested.
For example there was a club in South Florida (that doesn't exist anymore) which was notorious for having strippers who were G4P - only went one and never again.
