First Timer - What do I do so me and him can both get off?

So I'm finally going to get some after waiting a good few years of dating my bf and going through my horny phases. I know it's gonna hurt, that we should take things slow, and that sex isn't what I've made it out to be for the most part, but I want to help him make me reach that point of pleasure. I know it won't be at the same time, but I want to orgasm too at the very least. Any suggestions on how to get there?
