How do I tell him what I want?

Sharpie

There's this guy at my job. He was staring me down in a fuck me or fight me way for a few weeks (I was kinda staring back cuz he is hot) then he gave me his number. We've been texting and long story short, we started having sex but he had to leave. He said he likes my body and wants to teach me a few tricks.

I know that first time with him was kind of a fluke because I wasnt sure what to expect from him and I didn't adapt well. Now that I know, I wanna show him what I can do but I don't know how to tell him. I'm kinda shy in that area. I'm more submissive than anything but I really want to show this man what I know. Any tips??
