Now that I think about it, he isn't a true incel because he blew a chance. In college he had a girl that was into big dudes (like slept with multiple OL at his school, into big dudes) that was DTF, but he scared her away trying to turn her honest. Never even got to 2nd base.
My wife was mentioning how far behind he is now and how his woes compound. She mentioned it would be hard for a 30+ year old to date him because he wouldn't know how to do anything in a relationship. He hasn't been through his years of figuring out how to fuck a woman. He hasn't learned how this finger works there, or how tongues go in that motion, or how angles matter. He never had his 18-year-old just mashing it incorrectly phase.
Outside of the bedroom, she imagines he'd be a stage five clinger who would be desperate as hell to lock a gf down and would be jealous of everything. Basically, all the mistakes we made at 16, he'd have to do now.
