<human>: We've been together for almost 5 months and he's the sweetest, most loving and caring boyfriend ever. He cares about me genuinely and not the jealous or possessive controlling type. He would never start a fight or initiate one would always find ways to comfort me when I'm down. We're extremely happy in general, except there's one thing that bothers me to the max.
He keeps liking/favouriting sexy or photos of random hot girls or his friends on Instagram and Twitter. And half of his followings on Instagram are practically hot random scantily clad girls. (Not celebrities but girls that lives around the the city) and I'm not the jealous type either, I give him total freedom to do anything he wants as long as he knows his limits.
I know there's nothing wrong with this and it's selfish of me to find it annoying or make it an issue but it honestly bothers me a lot. So I'm wondering is this a normal thing that guys do? Even though they've got a girlfriend? I don't wanna bring it up cause I don't wanna make it an issue and I don't want to control him but I'm so annoyed to the point where I considered breaking up with him over it because I don't think it's something I can tolerate. (My ex boyfriend never pulled anything like this ) . Is it selfish of me to find this annoying and want to break up over this?

Give me a shortened version of the text
