Penis talk

My fiancé always brings up his penis. Example on my lunch break yesterday we were face timing he’s like u want to see something cool? I was like sure. He moves his camera down to his crotch area of his pants and points it’s my penis!!! I was disgusted what a turn off. Or I’m having a bad day and he is like what will make u feel better is my cock!! Or we could be talking about nothing sexual and he is like u want to see my cock or do u want to do it?! Seriously I want to tell him to shut up! But when I try to talk to him about it he gets mad like I’m the bad guy.
