I Want to Know Where You Are Ticklish

I Have a Ticklish ... Well, Lotsa Places...
Hi all!
My most ticklish places are tummy, feet, and underarms. Having my underarms, legs, and feet lightly stroked makes me, well, react, shall we say? Tickling my tummy and feet harder makes me hysterical.
I don't know where else I'm ticklish, since I've never been REALLY tickled. My wife's not into tickling at all. <sigh> maybe someday I'll find someone who'd love to find ALL my tickle spots!
