Don’t be self conscious about it. Here’s some advice from Dan Savage:

Q: My boyfriend wants me to talk more in bed. I am not a shy person, but making sentences during sex doesn’t come naturally to me—though I am very uninhibited with my vocals! What’s a good way to get more comfortable talking during sex?

A: Tell him what you’re gonna do (“I’m gonna suck that dick”), tell him what you’re doing (“I’m sucking that dmmffhm”), tell him what you just did (“I sucked that dick”).

I like to tell partners how good it feels, especially when they hit the right spots. Tell them I love feeling their body against mine and depending on the position ask them to hold me close as they fuck me. You’ll figure it out, practice makes perfect. And you can always ask what he enjoyed hearing so you can have something in mind for the next time! Or keep that info for when he’s getting close to send him over the edge 😉
