According to my ex, who prides herself to be a social worker and a conflict solver, relationships are built solely on sex, not on interpersonal connections. But then again, she also thinks that you shouldn't ever apologize because it shows a lack of self-esteem, called the police on her best friend because she was jealous of her hooking up while she didn't and regularly posts "memes" about how terrible everyone else is on Facebook. Maybe she's just a nutcase.
That may just be her, and I kinda feel bad for her. That sounds like a lot of maladjustment and projection. My friends say they had some regulars who'd start the sessions telling them about their lives and showing them pictures of their kids. Touch and validation can be a form of medicine. Everyone needs to feel wanted. We are social creatures. Incels are one example of those starved from such things.
