Was it when you were teens?
I went out with a girl with really sensitive nipples that did exactly that. I wonder if it's a teen/age thing - a bit like I had with He Who Must Be Obeyed when I was in my teens - a grope could get me to spluff in the right circumstances, but now I'm 35 I need, y'know ... some action.

Well,
She was nineteen if that helps?
It did for me.
If you expound that into a theory about age related turn ons it could explain a lot :(


Edit for your ninja reflexes.

There's never any excuse for lack of "action". At least, that's what I'd like to believe.
