Yea, I do agree with you about respecting females or anyone for that fact that is a doctor, banker, pharmacist or whatever a bit more than someone who fucks for a living, but then again I also respect those people more than ME, because I have no illusions about what I do, I make galleries and sell porn. I don't screw for a living but it's not like I'm contributing towards society either, but I'm going to school so perhaps I might actually contribute something one day.
I think both males and females who screw on screen are "prostitutes" but I don't mean that in a derogatory manner, it just is what it is. I don't disrespect them, because without them I wouldn't make any money. Also, I know a lot of pornstars like to "escort" and prostitute on the side as well. Not all, but I know some do, I've seen them advertise themselves on certain websites. So perhaps for some there is no distinction; whether it's being filmed or not, they are still getting paid for sex.
Also agree that posing nude solo is not prostitution , and if a female is doing it with a bf on-screen, well, they are both prostitutes whoring each other out, but it's much better than fucking 10 different new people, and not as bad.
