Welcome--I'm only entering the eighth week, but when you mentioned "numbness" I had to tell you--it was like my first post here. It goes away in about a week, and the breeze feeling too after about three or four. I think it may have to do with the sensory nerves on the skin were "disconnected" while the sensation of touch was delivered through the hair shaft. My guess is that the brain reconnects to the skin sensors once the hair is no longer receiving stimulation. But that's just my crazy a__ed thoughts about it. Have fun, and this place will answer a lot questions and give you a lot of great advice about you new Sly Life.
