A guy friend/coworker is confusing the sh! t out of me, is this normal?

read plsss !! i had a crush on him a bit ago, now he is just a hot guy friend (figured i couldn't really form a relationship w him and didn't know him that much so i moved on) . now we just getting to know each other (on friendship levels) and today we hanged out after work. we went to eat sum pizza and when we were done he suggested some ice cream. then he jokingly says "need to make some space" and farts. we just start laughing it off but im still in shock. while ordering ice cream he says he does it bc he is comfortable w me BUT that he has never done such a thing b4 (if it wasn't w his best friend or family); he put a bit of emphasis on this bit, then he got a bit shy n embarrassed (i kept teasing him about, all in good fun)

anyway, i talk about this bc is not the first time he does something like this (does/talks about xyz thing n then says how he does it bc he comfortable with me and doesn't really do this often/with anyone else). my mind wonders if he is interested in me in a way? or attracted? for even more context, he is a pretty friendly guy and is prettyy friendly with the other girls (going as far as to blow em kisses, to some, or calling each other pet names, but in very unserious way?) but doesn't do that w me as much, we do call each other names but not full pet names and we do hug n have a lot of physical contact but he is pretty touchy in general but sometimes it feels its a different kind of touch? there's a lot other things but this is already long af, hope you get the idea of it. pls help i can't keep overthinking this. is this a normal guy/girl friendship? (im f23 and he m22)
