How do I tell him?!

Me and my boyfriend hung out all of yesterday, and had the house to ourselves. So of course, we took advantage of our opportunity. We made out, stripped down and played around for a while. While I’ve given him head once before, he had never done it to me. So he flipped me onto my back, and has me pull my pants down. He asked me if it’s what I wanted to which I responded:

It went down on me and it felt amazing, I was moaning and everything...

Here’s the catch; I didn’t come. And while he’s pretty good, he’s not some kind of oral god. I want to come from him eating me, but since I’m rather new at this, I’m not sure what to tell him.

Question!

What does your SO do that drives you wild?

What do you recommend?

How do I introduce it to him?
