[Orgasm troubles] A little too fast??

So my boyfriend(20) and I (F17) have been together for almost 4 months. 2 months ago we started having sex in which I lost my virginity. At the time he came pretty fast and I thought that was normal as I was a virgin and it was tight. But almost everytime after that he still cums pretty fast. We do it like 3 times each time and I thought it'd last longer but he never does. I haven't orgasmed since we started and I'm starting to think I never will. So basically I'm asking if there's a way I can help him out or something.

TL;DR My boyfriend cums too fast so how do we avoid that?
