not neccasarily, i had friends who have a company producing (im assuming they still do i lost contact yrs ago) practically all aspects of ''adult entertainment'' from the phone lines, escorts, to videos pictures the whole shebang! they all practiced safesex without any exception, they had regular health check ups mostly the movie stars had originally began as escorts and phone work and those that hadnt had originally started out wanting to be models.
but i dont want to detract from the thread sorry!
