I heard the term pegging.
Might someone know what that stands for?

but there is a Wikipedia definition, and yet another term to be added to the definitions link.

I experienced this.  Don't knock it 'til you've tried it!!!

I've pegged a few willing victims, err I mean gentlemen, and didn't even know it

*oops, did I say that in my outside voice?*

I know a guy with an amputated leg below the knee, and he uses his stump, his "peg leg" to well you know...work the ladies.  

It is big and thick and few have been brave enough to try but the ones who have, love it!

I've become quite good at it, they tell me. The trick is to start small and work up only as quickly as the "pegee" wishes. Among my anal toys I have 2 strap-ons; one is newbie-size, the other is "Oh My God."

I've had only one male taker for the latter-- so far!

(But a girl can dream!)

But I think I will pass on that one.

A woman pegging a man doggy-style with a 4-strap harness and dildo, using the corner of the bed to adjust to the height most comfortable for penetration ... in other words, just strap on play with the man as the target.
