Dry humping questions..?

im 19 and very inexperienced.i have my first bf which ive known for a year but weve been together for a few months. he was my first kiss/makeout. we havent had sex. but yesterday we were making out, i was on top of him and he grabed me and began guiding me on him "dry humping" ifelt stupid cause i didnt know if iw as even doin it right or if there was even a poiint to it.. he kept breathing kind of hard and faster. does this mean he wants to have sex? how do i know if he liked it? he gets me pretty turned on but i dont want to have sex i want to wait, what can i do??
