You don't do anything you don't want to do. If you do something that hurts or you don't want to do it's your fault. It's always your decision as to what you do or don't do. You are correct most guys are not capable of getting an erection in front of a large number of people, lights, and cameras. Then fuck for an hour or more and cum on command. That is why you see the same guys over and over in professional porn. That really only applies to professional shoots.Something like onlyfans would be ok to help pay for hotels and lube but when you start getting paid you take the fun out of it and ****** to do stuff that hurts or you don't wanta do to make a check not counting hard to find a guy who can go the distance with out hours of fluffing
The real issue that I see is that it becomes a job. I know a lot of women who lose their desire to have sex without being paid and in front of a camera. You can avoid that by doing only what you want to do and keeping it fun.
