I can't say it's troubled me one way or the other.
I'm gay and I know it, but in my younger days I did have sex with three different women. Certainly money and cameras weren't involved, but I was functional every time. It'd be a lie to say it wasn't pleasurable, but I also knew it wasn't where my heart's desire lay. Each of those women knew I'd been with men, and didn't care and still led the dance, so to speak.
I've also had affairs with married men that were just as fully functional with me, but didn't leave their wives and kids for me either, and for all I know, didn't continue on with affairs with other men after me.
If favorites of mine like Paddy O'Brian and Colby Jansen identify as straight in their off-duty hours, I wish them all the happiness in the world, and still salute them for the performances and pleasure they've provided. Porn is product, and if that particular product stiffens my dick, it's successful. That's all I ask of it, and the private lives of its various performers is their own business, and none of mine.
