Porn is never going to be curbed and young men, under 16s, will always find a partner regardless of not being able to access prostitutes.
Pros don't mind dressing up to 'satisfy' fetishes. You and I may not want to do such things.
Some men will, regardless of marriage and children, be drawn to other women and better that his wants are met in a clean, well regulated place where he knows that he can find his requests met, than shell out for drinks etc in the hope of getting lucky in a bar after work.
