Men where are you at I need advice

I only see women answer in here but I need a man's perspective.

Short version : husband not interested in sex or masturbation. I've tried EVERYTHING. If I send nudes he ignores it. If I offer to do any nasty thing he wants he says no thanks. His hormone and health is all FINE. He says he's happy with me.

HELP! Talking to him gets me nowhere he gets upset and says he doesn't know why he doesn't want it
