Confronting a guy

Help. I'm currently on a fuck-buddies situation with someone I met from Tinder but we were on the same college/university, same building, same batch. We share too much similarities that we both can't deny the chemistry we have. But it's pretty clear we're both only after sex at this time, that it should be a no strings attached thing. We only get to have sex after 3 mos btw. Anyway he insinuated I was checking his IG activity when I asked him what's he doing, liking random posts on IG? There and then he knows I follow his activity and I'm pretty sure he does the same with me. Now, on our first few dates, I happened to talk about my close friend in college who's reallyyyy pretty, even complemented her with him and showed him her Facebook using my phone. Few days later I found out he followed her on IG. I was outraged af. I tried to not be affected by it and just deactivated my IG afterwards out of shock. He didn't confront me about my IG because you know, we have this NSA thing pretty clear but there's no denying the signs showing he's getting pretty attached to me. And here's the thing, now that few weeks later I reactivated my IG, (we just had our first sex few days ago in which it's his first time ever, yes I know in Tinder? But I should know after being in a 6yr relationship. He's definitely not a fuckboy at all and had no serious relationship before, only one lame enough not to do the deed lol) he liked all the 3 recent posts of my college friend exactly one day after she posted it all at the same time, same day I reactivated my IG. (Two days later he messaged me some vid on IG for the first time, something that would playfully tease me, confirming he knows I have reactivated) I'm feeling he's doing this mindfuck thing with me where I will feel jealous or something. Now I feel like I need to confront him about it. I want to tell him he can follow anyone he wants on IG but definitely not anyone who's associated with me while we are on this fuckbuddy thing. You know? Just out of respect? That he can do that freely after our thing. Do you guys think this is okay in a sense that he won't think I'm being unreasonable, clingy or crazy? What would you think would he say or happen? Please help need to get this thing out of the way
