I love clamping, and I realized that a stretch in the semi-erect clamped state (probably 50-70% erection) produces an amazing stretch in the tunica, and even in the ligs to a degree. I just angle the penis downwards with my other hand's OK grip around the base just above the clamp, and basically do a blaster type of semi-erect clamped stretch. Seriously, it is incredible, I suggest all who clamp try this out. If this is in Redzulu's guide then forgive me, I'm just trying to spread some knowledge.
