My husbands instagram

My husbands follows and likes on Instagram make me uncomfortable it's all women his whole feed naked women some famous which I'm a little more comfortable with some just good looking naked women that I have no idea how he found on there. He refuses to unfollow or stop following he says he's a man just looking, all men do it he wouldn't cheat on me blah blah. It makes me uncomfortable though, but I have no reason other than this to think he would or has cheated so like I feel like I'm just forced to accept it and do nothing?? I don't like it... (please don't give me a bunch of hate and say I'm insecure and stuff like I just don't like my husband looking at hundreds of other womens boobs everyday)
