Old Farts advice is right on the money.

Sex play can be a learning experience for you both...maybe you can teach him a thing or two about YOUR body.

*ooohh YESssss THAT feels good...OH NO! Don't do THAT!!..ohhhhhhhhhhhh yeahhhhhh mmmmmmmm*

Just make sure you're both verbal or that you're sending the right messages and cues to one another.

Lastly..HAVE FUN. And that's an order!
