Consent is conditional by design, it requires specific circumstances and/or conditions to be maintained continuously. The introduction of money or some material good as a requisite condition does not negate this basic fact.
Vanilla sex has always turned me off. I look for something deeper. That's why I reinvented myself as fetish practitioner. You can have sex and feel absolutely nothing. That's so heteronormative for it to be 'put penis in vagina and cum'. For me, sex is erotica.
I still remember I was so pumped in my first booking that the client had to tell me to calm down haha. It felt so easy and natural for me so I kept doing it. But it wasn’t until after several months into it that I fully comprehended the value of what I provide.
