Should I talk to him?

My bf recently told me he followed an ig model because "shes so fucking fit" not gonna lie it made me feel bad but I didn't though of it much till during one of our conversations I found who it was and due to curiosity went on her page and saw the kind of pictures/videos she was posting (basically all of mainly her ass in it, in lingerie, bikinis, videos of her ass shaking etc.), saw the ones he liked and it made me really uncomfortable, like I know is just some model he'll never get to meet but looking at those kind of pictures just doesn't seem right to me especially liking them. Also like 2 days ago he received a snap message from his friend of some girls story I didn't look what was it (he was sitting beside me watching tv so i could see what he was doing ) and he started acting a bit suspicious after like kept checking if I'm looking and tilting his phone away so I wouldn't see what his messaging and he never does that ( I always look away when his messaging his friends even when he does it in front of me) and idk it made me feel uneasy
