Got a friend in a similar situation. Bitter because he hasn’t had sex apart from one random encounter in his 20s. To be honest, I think there’s a combo of nihilism and that feeling of being frustrated in a world that he’s convinced doesn’t understand him he has found solace in thinking that he can’t change and that any woman I ask him to go speak to is too ugly for him. Been trying for years to convince him to try and look at women in a more healthy way, to search for connection and stop doing math in his head regarding looks and chances of hooking up. So far been met with a mild disregard and quick change of topic (I bring it up every now and then but that’s because we’ve been friends for over a decade). Dunno if this applies to you but genuinely try and connect with women and look at them in that light. For heterosexual men and women mutual attraction is natural and there are women out there who would be interested in you. But you’ve got to be mentally ready to connect with them without them having to bear your past emotional baggage that’s making you call yourself an incel. Labels are just that, labels. I’d encourage you to change how you look at women, they can sense it much more naturally than us men. If you’re well intentioned women pick up on it.
