Sorry guys this is laughable!
You guys are making this waaaaaay too complex.
Sex and food, are among our basic requirements.
Do ANY OF YOU HAVE A PROBLEM GOING TO A RESTAURANT??
No....I didn't think so.
You go to Thomas Keller, or David Chang, or that great sub shop down the street because they have a specialized skill that they are very good at...likewise a sex professional if you're chosing right should be able to deliver a killer performance of pleasure.
are there home cooks as good as restaurant cooks....yes...but you don't go searching for them, that would be inefficient..YOU JUST GO TO A RESTAURANT.
roman soldiers had hookers rationed to them....basic needs...think about it.
Oh and Backbreaker to your point, sex is never free you're just paying in installments
Paying upfront for a sex act done right is the biggest BARGAIN you'll ever see.
