Been to that website already..Didnt really explain much on how or why this ticklin occurs. All I do is focus on that part of my brain, and it starts to tickle... Actually its kind of hard to determine if its just the top part of my brain, since i think the feelings starts to move toward the forehead area. If this sensation was a little stronger, i could easily have a mental orgasm whenever I wanted! That would probably take practice...if thats even possible. Much respect.
