I think if a girl works in this profession she should be open minded about little things like clothing requests from customers. I have clients who prefer me to leave on the stockings, bra etc and some who want to see me naked as soon as we enter the bedroom, I am fine with both.
I am a more mature woman so not in my 20s anymore, even though I go to the gym and do lots of crazy exercising to keep my body in shape and a small size, I am mature and have the body of a mature woman. Clients who will book me will know that, my real age is clearly stated on my profile, so is my size etc. I don't feel the need to hide anything to feel confident and sexy.
It's not a secret that women are always struggling with confidence and body issues, but that's something that shouldn't affect the job.
