Hey...
I'm of the playful mindset too....don't really like the idea of being tied up and tortured! Its good to know there are some others around :) I assumed (perhaps wrongly) that most guys see tickling as sexual, which has generally put me off giving 'sessions' a try.
Hey.... here's an idea: How about paying by the minute, that way it is kind of a game..... with an incentive to endure the tickling for as long as possible?!
