Oh FGS. Decriminalisation doesn't work, criminalisation doesn't work, because by its very definition it's about pushing the boundaries of what women are prepared to put up with.
Look at porn, which has become boringly mainstream, so what happens? It gets nastier, dirtier, more violent and with more risk to women.
The only way these things will stop is when there stops being a demand for them and that will only happen when the men WALT start seeing women in a different light. And when the social stigma and physical ramifications of sex for women are removed, thus putting them on an equal playing field with men (as JM has finely pointed out)
I'm not holding my breath for any of those things to happen, although I would like them to.
