I used to let men take pictures of my private parts for money
Did you like doing that?
I regret working there. The boss treated me very badly.
Even though you didn't like the work it is okay to charge people for your photos. It is your body and you can do what you want with it.
It isn't okay, I'm just doing this for money.
It sounds like you might have some residual trauma from your time working that job. I think it would be good for you to talk to a therapist about how you feel about that part of your life so you can move forward.
