Am I being dramatic or?

So, my fiancé is a great guy. We're expecting our first little peanut 🤰🏼💕

But I've got a slight problem. I just happened to fall upon his Instagram, come to see that his "following" list consists 80% of half naked chick accounts, models, he's even got an old milf page he follows. Nothing but fat ass and titties. Everywhere 😬 which me being a little self conscious, I have small boobs and I'm a whole whopping 108lbs.. so there isn't anything thick about me. It kinda gets my esteem down seeing how much he likes to look at that stuff and that's all stuff I don't have.. I don't have a problem with a handful of him following accounts like that, he's a guy. I totally get it. No problem there. But the extent of his account is starting to really erk me... am I just being dramatic over it or am I reasonable for being a little grossed out about it?
