The forbidden glans rub
Well as you know Dr. Linn forbids rubbing the glans underneath. But he is a quack so who cares what he says.
For months now when I balloon I often do a soft circular motions rubbing the top of the glans. This can be very enjoyable. I found something even more enjoyable. Rubbing the underside of the glans. Watch it! When you do this technique it can send you into multiple dry orgasms. But rub gently with lots of lube. This underneath the glans rubbing can be uncomfortable if it is done to harshly.
Speak softly carry a big dick, I'm mean stick!
