I do think the whole situation is getting worse, and not better though.
I was reading an article recently about the rise in women selling 'personal' interactions via webcam, where they entice punters into a private chat room, and then once in, do what the punter wants via video, for a fee.
The bonus side of this is that you don't have to physically touch someone who's so unappealing to you, that the only way you'll engage with them is for money. And so it's obviously a lot safer - no risk of GBH, gagging, tearing, STIs, pregnancy of course, etc, etc.
But the overall picture shows that the demand for sex from men is only increasing, thanks mainly to the internet.
I know some people don't like my idea that because men and women come at sex from such vastly different vantage points, it possibly goes some way towards explaining why men (as a group) feel able to buy sex.
It's fine if you disagree. But the only way we will understand why so many men - across countries, cultures, religions, upbringings, pretty much everything - feel comfortable and able to buy women's bodies for their sexual use, is if we try to understand what is going on their heads.
DWH, for example, sees mutual desire only as an ideal. That instead of trying to tackle that from perspective of teaching (Christ... ) men about consent, we should instead make it easier to access and use prostitutes. This is really enlightening. There's probably a zillion and one reasons why men feel able and comfortable having sex with a person whose consent they have to buy. I think we need to understand those reasons if there's ever any hope of eradicating prostitution, because I honestly see it getting a whole lot worse, not better.
