So when we were making out....?

i went to this party last nite and we were drinking. there was this guy there that ive liked for a long time but i have kinda moved on, we r still just friends. me and this guy snuck off to makeout and we went down the street and around the corner so no one would find us. he was actually teaching me to makeout cuz i had nvr done it b4 (i am almost a senior in HS and he jsut grad. from HS) well we madeout a bit and then we were just stading there so i went in again and while we were making out he pulled me closer so out bodies were completly touching and he kinda moaned but it wasnt loud. then when i pulled away, he was like "wow....that was....umm...that was good....rly good....that was.....perfe....umm....yea that was nice....wow." so what did that mean? why did he pull me closer and y did he moan and was it actually perfect or was he just trying to make me feel better?
