Up until a few years ago I had never even thought about doing that, never heard of it actually. I discussed it with Doc one day and he made it quite clear that doing so, either receiving or giving would be a strict hard limit. Well more often than not when Doc says "hard limit", I hear "please tie me up and do it to me anyway". Hehehe. Seriously, I do respect his hard limits, or any limits, but on reasonable things like no hanging him from hooks in his back, stuff like that. But believe it or not, spanking both giving and receiving was also a hard limit for him at one point too, lol. And now he begs me for it, and loves to give it. I always know when he voices a "hard limit" out of fear of the unknown, or out of pure common sense.
I digress. So one evening I shaved him bald, front and back, another used to be hard limit by the way, another in which he loves for me to do now. So I knew he was very clean back there, and just for the hell of it, and because I knew it was an invalid hard limit, I decided to take a chance. Lets just say there was quite a reaction from my Pumpkin Head. And, this is no longer a hard limit, either giving or receiving, lol. And might I add, YUMMY!!!!!
