>I think that there are enough men who have sex only with prostitutes, for whatever reason. Be it temporarilly or for the rest of their life, some men can't find a woman who wants to have a relation. Maybe because they have a handicap, maybe because they are 'unattractive', maybe because they are simply not nice enough in the eyes of all women they meet, maybe because all women in the environment are already occupied, whatever. All more or less valid causes, in my eyes, for not having a relation. Nonetheless, these men too have sexual desires. Prostitutes help them there, and so they also help society. They are like social workers.
Then we need male social workers as well. I see why there would be an equal, maybe larger, number of women with the same needs.
