I've read a little about thumb testing but the more I want to stop overhoning and the more I want to improve my honing I realize I need to learn what it feels like when you guys do a good thumb test. I understand the basics but, for example after reading the barbers manuals again last night (I love those things) I want to ask a question or two.

One, my edges stick to my thumb nail and "dig" no matter what. When I touch the blade to my thumb (the skin at the ball) it feels sharp. More honing it feels sharp, less honing it feels sharp. I know I'm supposed to wet my thumb for 20 seconds, but what am I supposed to feel? How does a blade feel sharp, or sharper, or less sharp? The only sensation I have is the edge of the blade moving in between the ridges of my fingerprint. Do I need to feel the blades sides somehow too? I mean if I gently touch a kitchen knife I can get the same sensation, so what am I missing? Can anyone describe the feeling of sharp?
