Maybe I sound like an old fuddy-duddy, but I think that hook-up culture and porn have taught people to engage with each other as two-dimensional sex dolls, which can't possibly be satisfying for anyone. Even very casual sex should be two human beings connecting with each other on a variety of levels, which gives me a story idea about why I/we sometimes pay for companionship - because we know we will have a good total experience, with fun, and good conversation, and well as good sex. Considering the current dating market, it's well worth it.
