Bf liking girls photos

What do you think about your bf liking those kind of photos? My bf said he was following this model on insta (he followed her before we got together) and I never heard of her so I went to check her page and he liked quiet all of her photos like this ones, like he can follow her if he wants but it kind of made me uncomfortable that he liked those kind of pics.... am I the only one?

Does it make a difference for you if they followed them when dating you? Or not difference at all?
