The whole reason for paying for sex is to avoid treating the person being paid as a proper human being.
To be able to try things or do things their partner doesn't like or says no to. To avoid having to treat them as a person and with care, essentially.
It's been so normalised as well and that bothers me.
When I was young men who paid for sex never talked about it, it was seen socially as an exploitative and pathetic thing to do. The men knew it was 'wrong'.
Now we have articles in mainstream media about women making loads of money, almost exploitating the men, it's not unusual on stags, and again in the media we get all this stuff about poor men who can't get a partner another way, especially men with disabilities. Amnesty Ireland positioned sex with another person as a human right. And certain types of feminist are all 'sex work is work'.
I have had a man I knew tell me when he was pissed that he had paid for sex. He explained that it was the only way he could get it due to a condition (which I had never noticed and was pretty trivial). He told me... Why? I think he wanted sympathy and absolution. I gave him neither. He's married with kids now.
I think the reason so many women are against prostitution is totally misunderstood by many men as they are utterly unable to see outside their own viewpoint. They assume, always, that women view prostitutes as a threat, and look down on and despise the women.
The truth is, for me at least, that as a woman who knows what men can be like, I can well imagine how it goes. With a big helping of 'there but for the grace of God go i'.
