One of my friends tried the webcam business, joined an estabilished cammer friend for some lesbian shows. She got doxxed, and the amount of creepy messages she got made her entirely leave it.
I knew a girl who was active in the S/M scene abroad in a richer country, she made crazy money (at least compared to salaries here). She loved being a domme. We drifted apart a few years back, due to covid and lockdowns, but she might still be doing it.
Several of my friends, who did modeling, turned to erotic photography (sometimes with other girls, sometimes with current boyfriends), but none wanted to do anything with random guys, so they all stopped there.
One of my friends used to be a rope bunny, she really enjoyed just being there, completely giving up control, but she only wanted to do that while not in a relationship, so she stopped a few years back.
I also knew a guy who did porn, an ex-colleague, he said the money wasn't bad, but he had to use chemical cocktails to keep his dick hard for hours during shoots and that started to wreck his mind, so he left the business.
