Because the majority of men are motivated by images to the brain where only a small minority of women are.
More to the point there isn't the same social pressures on women as men. Women grew up encouraged to not have sex, men grow up viewing it as something they deserve and are entitled to and that getting makes them a more successful person, the way getting more money or more food does.
I remember conversations at school where people were saying if I couldn't get laid, I'd buy a prostitute or rape someone. Because both of these things were seen as preferable to simply not having sex.
Look at the whole "nice guy/friend zoned" phenonomon where the basic idea is that if you're nice to someone who was tits she owes you sex.
Legalising the sex business reniforces the idea that sex is a commoidty, one you should buy if noone gives it to you. You are breeding rapists, in the same way trade breeds shoplifters.
