Sounds like he has some ideals that root in toxic masculinity and the belief that as a grown man he doesn't need physical comfort anymore. Might be that he's hurting or withholding as well but sadly that doesn't mean he will change his attitude or opinions. I'd recommend to think of yourself first and if you don't get what you need, don't bet that he will change, get out. You're still young and don't deserve to be this empty.
