|"How much longer do we have to cuddle before I can turn the TV on?"|
"I hope she doesn't ask what I'm thinking."
Stop trying to read that blank stare on his face; he isn't thinking about shit. If he is then it's a medley of images, sounds, past and present events, that song he hates but can't get out of there, and why he keeps burping up hamburger from two days ago.
Here's what you need to know: He's more than likely not thinking about anything that has to do with you. Yeah, I know you two just got through screwing but... no.
We zone out-- that's it. Let a grown man get a quiet moment and he'll disappear into it like another dimension, freeing himself of outside stimuli and perhaps regressing to a time in his life when he was stinky, happy and easily placated by shiny, moving objects (yesterday).
This is especially true just after sex when most of what's occupied his thoughts has been flushed out in a ten-second Hallelujah! of ecstasy. (Note: If it was a casual roll, then he might be thinking "How do I escape?" unless he's already got it planned out.)
So before you ask what he's thinking, consider substituting another vital question: "When's the last time you had something to eat?"
