Are you sitting comfortably? Then I'll begin. Go and find a mirror that you can lay down on a flat surface. Yes - that little prop up one from the bathroom that you use to squeeze your blackheads or pluck your beard will do fine. No, you don't need the magnifying side.
Right, pop the mirror down on the table. Coffee table, kitchen table, wherever you happen to be, doesn't matter. Now look into it - no, leave it on the flat surface, don't stand it up. Lean over the mirror.
How do you look?
Just fine and peachy - not much different from vertical, really? Good, then you can go away and need read no further.
Are you in horror at the jowls swinging forwards? Is that a really horrible sight? Are you running away screaming?
Well let me let you into a secret. This is the view of you that your Other Half gets when you clamber on top. As you ride enthusiastically, looking lovingly down at him from on high, the only thing he can concentrate on is your jowls. And possibly the slap, slap noise your tits are making as they go back and forth. (That's why he fondles them - to stop the noise.)
This is why your OH shuts his eyes - he's not concentrating on his orgasm, he's shutting out the picture of those jowls.
Time to stick to missionary or doggy or try the reverse cowgirl, maybe?
Have a nice evening.
