Mixed signals or just overthinking?

A little over two years ago, my friend & I decided to become ‘fuck buddies.’ We are only seeing with each other, we always use protection & also do have our yearly checkups (had mine last week, he had his early October.) We both agreed that there were no feelings for each other, we both didn’t want a relationship & told each other that we can call it quits at anytime.

For the past two years we have spend most every Saturday with each other, (from 2pm Saturday til 2am Sunday morning on average), he has spent the night at my place & I have spent the night at his. & throughout the week he’ll come visit me at my house at night & viceversa.

These last couple week has been different though & I just believe that I’m overthinking it but idk. He seems more affectionate than usual, it just the way he holds/cuddles me & the amount of kisses he gives me. I don’t wanna ask bc I don’t wanna look awkward & it just mean nothing, but something just feels off.

Usually before & after sex we cuddle or just lay down. More always in this position or with me lay on my stomach head turned looking at him & him laying on his back like the guy in the pic below.

But lately it’s been more of him laying like this before (me on bottom & him the one laying on top)

& like this after.

He gives me more kisses as well like this while in our new cuddling positions. (The cat is me being all confused about the situation, haha)

It’s nice & all don’t get me wrong, but it just throws me off a bit bc these past two years it just been like the first image. Idk if I’m just overthinking it or not, I could be wrong & he now has developed feels, what do y’all think?...
