Ever try just rubbing the top side of your cock? Did you cum that way? Was the sensation any different?

No longer available.

I have but it makes the head of my cock sore.

Yes....but it was awkward. I remember at age 11 when I first (and accidentally) began to masturbate, I woud hold my cock with my left hand and with some form of lube on my right, I would rub just the glands. My fingers outstretched just the palm touching my glands and making small circles over the head. It was awesome, highly sensitive and a new experience. Later I saw older boys do the ''JO'' motion, talking and laughing. I figured, that's the way to do it. Went home, and it took time to get use to it. But....... still do it.....and enjoy every second of it.
