I agree escorts aren't willing to bang the guy out of genuine desire.On an old incel board, it is clear that when you pay someone for sex then they are not willing (ie out of genuine interest) to have sex. The definition is sex with a willing partner. If you pay for it, blackmail, rape, etc... then its no longer willing. There is also the possibility of trafficing, the girl being molested at a young age, etc.... Most.of these women are not normal women that woke up one morning and decided to do that. Since its just impossible to know the history of every escort you deal with, even on that level, its a challenge to really establish willingness.
Calling an escort an unwilling partner, I take issue with. I recall a viral tweet from a feminist where she said "When you buy an escort, you're not paying for consent. You're paying in lieu of consent. Prostitution=rape."
For obvious reasons, I don't like hearing clients get called rapists.
Is paying an escort for sex really a whole lot different than a civvie banging you because you bought her dinner? If a civvie is only willing to bang a guy if he buys her dinner, can you really call it genuine desire?
As for trafficking, it's true some escorts are being trafficked. It's next to impossible for the client to be aware. So I'd still say the client is doing nothing wrong.
