Isn't that what some people on here believe? You have some posters believing that people need sex like water and cite Maslov's pyramid of needs and think the worst thing you can be is incel. If you have that mindset then the OP has actually made the right decisions. As long as he's not using escorts, watching porn, or God forbid, subscribing to OnlyFans, or fapping, then he's not at the bottom of the barrel even if he has to put up with abuse, has no self-respect or dignity, as that's secondary to being able to have unpaid sex right?
Lets face it, there are at least mixed-messages on here about how valuable sex is to the point I can't even fault the OP. He might listen to your advice, but then he might read one of
@SW15 's posts too and then do this. Also, with all the talk of the dating market being too toxic, and if all the options you have is your ex, and a choice to be incel or have someone, then I can see people making the same choice as the OP. If you have no options then you put up with abuse or be celibate.
