Performed on the halfway tumescent penis, jelqing is a manual manipulation of simultaneous squeezing and stroking the shaft from base to corona . Also called "milking",  the technique has ancient Arab origins.  Despite many anecdotal reports of success, medical evidence is absent.

I decided to hedge my bets and ordered all five products, BIG mistake! I’ve had to spend so much money on hiring a seamstress to modify and enlarge the crotch of my pants, that I can hardly afford to go out on dates. Being overly large, I have found that my gait has changed resulting in hip and knee pain, which required a hip replacement and physical therapy, luckily, these procedures were free, due to the free health insurance given to all Americans under “Obamacare”. Whew, imagine how much those procedures would have cost if those damn Republicans had gotten away with blocking such a wonderful non-tax! Honestly, if someone would invent a pill, that makes you smaller, I’d be first in line for a year supply. Be careful what you wish for, you just might get it.
