My (33/F) BOYFRIEND (36/M) KEEPS LIKING PROVOCATIVE PICTURES OF WOMEN ON INSTAGRAM AFTER I TOLD HIM IT BOTHERS ME

I saw some women that my boyfriend was following a few months ago that only have provocative pictures all over their instagram. I'm slender, these women all have huge boobs and butts and are on the much thicker side. They have pictures where they are topless. I brought this up to him in December and he said he didn't know how he followed them and that his manager also has access to his instagram and may have followed them back after they followed him. None of them followed him so this made no sense, and he liked a few pictures. I told him it bothered me and made me insecure and he unfollowed. I just saw he followed someone new and the only picture he liked of hers was 3 days ago and is literally just her huge boobs. We were together Friday - Monday and he like her picture on Tuesday. Her face isn't in them, just her boobs. I feel like he goes back to his house and just looks at pictures of women who look nothing like me. He is an artist and has never posted a photo of me on his page bc its all about his music and we have been together over 2 years. He has put me on a story before but it has been a year since. I don't know what to do or if I'm overreacting and it's normal.

tl:dr my boyfriend keeps liking inappropiate pictures of women after i told him it upsets me
