Yes, very much so.
A little bit, yeah.
Sometimes, depends on my mood.
Nope.
I don't know.
Very much so, My Girlfriend tickle attacks me all the time and I always roll around like a helpless seal nearly in tears of laughter xD
Not too much, the skin thickened too much over the years.
I still get goosebumps when ants or bugs crawl over my legs, which helps to shake them off without hurting them.
My palms aren't ticklish, but my feet and my back are.
