Boyfriends instagram full of photos of half naked girls

My boyfriends instagram suggested photos are LITERALLY full of sexual images of girls. He used to have them all over his liked photos but i got rly upset.

Hes still looking at it obviously as its all over his instagram page. I tried to shake it off but ive been seeing photos and videos of girls saying to leave him if hes social media looks like that so i dont know if i should be getting on to it. What do yall think?
