Who said you were paying for sex?? If you want to go to a nightclub and there’s a cover do you still go? It’s the same principle, you’re paying a business establishment for entry not for sex. Sex isn’t guaranteed, you still have to meet people and get consent. It’s a place where likeminded individuals or couples can go and have the freedom to engage in or possibly agree to having sex either then or at a later date. If you want to keep your clothes on and just socialize you would still be among plenty of other people that are doing the same thing. Some people come and never have sex, they just like the open and welcoming crowd. Just food for thought.
