The way I see it, it's not too hard to understand. You know how people tell others who are nervous about meeting someone, or speaking to a crowd, to picture them naked? The same principle applies, but it's even worse with porn chicks, strippers, etc because you don't have to use your imagination. People see you naked shaking your ass, sucking multiple dicks, and getting nutted on are just not gonna take you seriously. Coworkers who can pull up videos of you on their phone in the break room getting gangbanged or swallowing loads of nut are going to look at you differently. Once people know that you'll have sex for money, their opinion of you is going to change.
