I worked with the vice squad in a large Police Force some years ago, things may have changed but I can say with personal knowledge:
Men were arrested and convicted for raping prostitutes
Men were arrested and convicted for robbing prostitutes
Men were arrested and convicted for assaulting prostitutes
We knew the girls who worked on the streets, we had good relationships with most of them, they regarded being arrested and fined as a cost of working and obviously if they were taken to court and fined the way they paid the fine was to go back out and work.
Girls were forced or coerced to work but equally for some it was a choice and for a few it was the family business.
Persistently soliciting was an offence, selling yourself for sex wasn't and I believe isn't.
Working out of premises does not constitute a brothel, more than one person needs to be using it to make it a brothel so if you want to "entertain" men for men in your bedroom then it is your business.
I knew prostitutes who paid tax, sent their kids to expensive private schools, invested their money wisely and intended to get out of the business when they had made x amount of money. I knew girls who used drugs and alcohol to enable them to work, who were abused by "boyfriends" and punters and were old women before they were 30.
It is a very complicated area and there really aren't any easy answers.
