What a bizarre expression really.
"Full penetration"..
As opposed to what?
I mean.. As soon as you stick it in it's..well..in. Why would it matter after that how much. Obsessing over the amount of penile penetration just seem a tad voyeuristic to me hee he.
Like HALF flaying a cat alive wouldn't be as bad?
Oh well. Not really on topic this tangent of mine. *goes away*
Peace.
