Oh my friend. With all of that intelligence - you should realize that the human tounge is very tactile!

It can bend into all sorts of configurations... it's softness and nearby lubricator (best applied, if you have that gene that allows you to roll your tounge, with a slow drip - of just a few drops - but never via spitting!) can be pleasing. At least the women I've paid say so, lol.

It's proper use can yield a softness not possible with fingers, and when the moment is right - can yield firmness and warmth.

My only problem with my tounge is that, well, it is at times too damn close to my teeth. As my ATF once said. "Hmmmm, don't know what that was - maybe your teeth?"

Save the fingers for something else, like typing stupid comments (as I'm doing) on TER.

VOH
