How many half naked girls is considered normal in a guy’s explore page on IG?

My (F20) BF (M20) and I were hanging out and he was on his phone while I watched netflix, then he stopped scrolling at what sounds like a thirst trap audio so I turned to look, turns out it was just some paparazzi pictures of Kylie Jenner and another model in bikinis on a yatch.

We’ve previously established that it’s completely fine for both of us to watch porn to get off and I have no issues with it. But seeing him caring enough to click open a post like that when he’s not horny kind of bothers me a little…

After that he agreed to let me look through his explore page, and even though most posts are about sports, gym, cars but there are quite a few girls here and there… Just for context we live in a conservative country where most people cover up in public and nobody really wears bikinis publicly.

I do want to emphasize that I have been cheated on before and have serious trust issues, but I don’t want to jump to conclusions and I try to be really careful so im not a ‘crazy gf’, so please no hate.

should I be bothered by this and tell him to stop looking at girls, or is that unrealistic and it’s only normal that a guy does those stuff?

TLDR – Saw a few half naked girls on my BF’s explore page, should I talk to him or am I being unreasonable and setting unrealistic standards?
