Okay, so there are painful and pleasurable shafesfifts depending the story. I've not really seen if its pleasurable some new shifter trying to do it again and again for the sensation.

I mean, I know I LOT of people that if it were the least pleasurable they'd be at it until something stopped them.

Then I started wondering if that whole myth about if you do something too much you'll get harry palms actually could come from a situation like this, where excessive shifting means some fur hangs around in human form.
