The fact that this is even a question shows how serious this is.
Since when is it rape to pay someone for a service they offer?
This tells me so much of what you understand about women and women's sexuality.
In no way is prostitution like any other type of work. In no other line of work can your customer or boss impregnate you, regardless of contraception usage. There may be similarities, but on visceral, primal level it is different, and men who don't acknowledge this are a massive red flag.
Having sex with a man you're not attracted to is not the same for women as it is for men. This is why women can retch or vomit after they've done something like that. Yes, for a very small minority, they might not mind who they have sex with for money, but most end up doing it out of desperation, no matter what they tell you, or end up relying on alcohol or drugs to anaesthetise themselves to the horror they subject their minds and body to.
You put yourself in such a vulnerable position with someone who could literally kills you with their bare hands AND impregnate you if they wanted to. The power dynamic between men and women having sex is massive, and not something you can wave away because sex happens to be different for men, or because there's an exchange of money.
And then there's the number of women who end up doing it because they're addicted to drugs or trafficked.
It may not be nice to think of yourself as physically repulsive to a woman, or that a woman only had sex with you because she was absolutely desperate or coerced to do it, but this is the reality for most prostitutes.
The men who insist otherwise just don't have a clue what it's like to have sex as a woman, or are trying to smooth over or justify something they know is contentious and unethical.
Why am I even wasting my words. You've clearly come on here to justify your activities and your past.
