what else you should do to guy unstead of sucking on their penis when your having sex??
Anything. Moan, say his name, run your hands down his back or through his hair, squeeze his butt, jump on top, nibble his shoulder, tell him what you want him to do.
There are so many different ways to make people feel good, just ask him! Chances are if it's too awkward to ask him, you shouldn't be engaging in this type of activity.
Plus, its kinda hard to give oral and have sex simultaneously. Unless you're reeeally limber...
How about have him worry what to do for a change?
