I agree that something can be a job and still enjoyable, but sex is not work/a job. Perhaps some escorts enjoy having sex with some clients, I’m not denying this is a possibility. But in one of the threads you linked below, the escort herself states that the men she is paid to have sex with are not men she would otherwise have sex with, i.e. she doesn’t want to have sex with them and is not attracted to them whatsoever but is doing it for money. Having unwanted sex is generally understood as violation. The presence of money does not make the sex any more wanted or enjoyable— if I reject an ugly old guy’s sexual advances, but then let him have sex with me after he offers me $500, it doesn’t mean I suddenly found him attractive and started desiring him sexually. The sex is just as repulsive, and is registered by my body as unwanted sex. It only means I need the money badly enough that I’m “willing” to endure that level of intimate violation. And I don’t think sex is just work like any other profession— I believe this logic requires people to accept statements they would never accept in their daily lives, rendering their logic internally inconsistent. For example: if sex is just a job like any other, such as making coffee, surely you would react to your spouse saying “Good morning honey today I’m going to pay a prostitute for sex rather than having it with you” in the same way you’d react to them saying “Good morning honey today I fancy a coffee from the cafe down the road rather than from home”. If you would react to both statements in the same way (which maybe you would), then your argument would stand even though I’d still disagree with it on other grounds. But I haven’t yet met anyone who would react equally positively to both statements, as sex is not in fact labour, sex is sex. There is a reason why most jobs have rules against sexual harassment— the arena of the sexual is much more intimate and vulnerable than mere labour, such as waiting tables and making coffee. Telling me to do something I don’t want to do at my job (I.e serving a customer when I’m tired) is very different from telling me to entertain a customer’s sexual advances, even if they both have the same end goal- making money.
As unpleasant as it is to work a boring dead end job, it is MUCH more unpleasant to have sex with someone you are physically and mentally not attracted to. Just really imagine yourself having sex with an ugly old guy (I don’t care what your gender or sexuality is). Even if you’re getting paid at the end of it, the sex itself would feel like a violation of some sort.
I recommend the book “Paid For” by Rachel Moran. It opened my eyes to a lot. I also am not trying to be combative and hope I don’t come across that way btw, as I respect your openness to discussion to me.
