He Doesn’t Reciprocate Oral

So I’ve been in a relationship for 4-5 months. Im 15 & hes 17, we go to different schools so we don’t see each other a whole lot. When we see each other I always give him a bj & he says a lot that he’s gonna finger me and stuff but he never does. Just today we were in my room and we cuddled and then after a while I ended up giving him a bj. He said he’d finger me if I took my pants off & after a while I did & he did Nothing. Has it taken anyone else’s bf along time to start reciprocating? What do u guys think I should do?
