So I have really been working on this Mandingo stretch! I just wanna run it by the group. After gripping penis at glands, pulling, and twisting penis 180⁰ ( head now facing my stomach. I have my shaft up against my outside knuckles, i push my fist down on shaft, for resistance, and roll my fist up against my public bone. Not sure if thats a Mandingo, but boy it works wonders for a flaccid stretch! Instant results, after a 20-30 sec hold, with decent force applied.
