I love constrictors. They have basically been my only form of Penis Enlargement for the last couple of months. I seem to be gaining very well from them, but I won't be measuring for a while so I'm not totally sure. I do love the constrictors though. Yum, Constrictors!
All day clamping is good too. I did that for a while with a hose clamp and found a good formula.
ADC+GF=GIRTH!!
It's easy! Just put on your hose clamp, make out with your girl for a while, and voila! Red spots galore on your penis, and you didn't even have to try. It's great if you know you'll be tight on time. Try it out sometime.
