Grim stuff that. It amounts to, in the western world I think, about 1% of men as habitual users of prostitution and 15% who try it at least once in their lives? While advertising and education may lower that 15% I doubt it would ever change that habitual percentage. Making it illegal would dive it underground, foster crime and worse exploitation I would think.
I just cant understand the male head-space of prostitution use. I knew a dad many years ago who was 'good mates with his son' who told me he had paid for his son to lose his virginity. He was quite serious, he told me quite proudly, like is was all part of sharing some kind of 'mens club/mens initiation' business. Oh god that was vile. Aside from him I got to know quite a few different men who used prostitution services, a side effect of working for many years in a shop only a few doors away from a large legal brothel.
They were a very weird mix of men, some were utterly odious and vile creatures, successful and proud pure 'users' with private opinions of women fit only for toilet walls, though publicly they could be as charming to women as anyone could be. Others were ..hmm... quite lost and pitiable. They were awkward and dysfunctional in their ability to deal with women socially. Others seemed deluded... not sure if that's the right word though, they seemed to think the women they paid to have sex with actually enjoyed their company and the experience.
