Please help me out

My boyfriend has many guy friends added on social media & these guy friends share a bunch of half naked girls. It bothers me so much that those things constantly come out on his news feed, daily.. i have talked to him about it & he tells me " i cant control what other people share" & automatically gets mad & calls me crazy, insecure, etc

I know its a little childish, but i cant help to feel so hurt knowing my man is constantly seeing his friends share ass, tits, naked girls. Is this worth leaving him? Or what should i do ... besides talk to him because i have a million times.

& at the same time, he never wants to have sex. & we are barely 23.. so that really makes me believe that this relationship will not work out. We have been together for 4 years.
