Is he catching feelings too?

So me and this guy have been friends since 6th grade and we’ve been sexually attracted to each other since then I guess (he always liked my body and personality). We’re older now and have started to take things to the next level (I’ve been sitting on his lap for example, he caresses my skin/body and he acts differently around me/treats me differently than other females he knows. At least when I’m around). I think I’m catching feelings for him now and I’d like him to feel the same I think. A part of me feels he just talks to me for sexual pleasure and school work (we like to do assignments together, plus we have a class together this semester), but I actually am comfortable with him and he’s comfortable with me, we laugh with each other and we bond over things. But he never texts first, but when I text him first he replies quickly (like within a minute). I don’t want to seem desperate so I guess I’ll leave the texting alone. I catch him looking and staring at me whenever he thinks I don’t notice and when I look in his direction he looks away quickly like he was never looking at me at all. It confuses me a lot and don’t want to ruin things with my feelings. I guess I could say we have a “friends and with benefits” kind of relationship.
I’d just like to know he is catching feelings for me or just using me for his own pleasure. I know that we’re young (almost juniors to be exact) and shouldn’t be thinking about sex this soon, but we comfort eachother at this topic.

Sorry if this is too much to read, thanks!
