I wouldn't. If I were to ever do porn, I would need to hide my face in order to have plausible deniability in the real world. A porn studio probably wouldn't accommodate that in a fucking scene. Second, I wouldn't get aroused off of the idea. I could take Viagra, but I wouldn't enjoy what I was doing so I would probably give a bad performance. Third, I don't think there's enough financial incentive for me to do porn anyway. Costs too much to break my mama's heart, that's what.
