When I have a 60-65% erection, I often take my cock (in a seated position) by my right hand in an 'OK' grip, with the palm facing the floor. Then I tighten the grip and pull down firmly, and hold it for 15-20 seconds. I do about 5 sets of that. And when and after I do that, I feel some burning in my ligs. I did this without doing any real research in the HUGE library of Penis Enlargement techniques (well done, DLD!). Does this technique have a name already? I'm curious.
