The force you need to apply is just enough to induce micro-tears in your penis tissue. Fortunately, this is way less than 3 lbs. of force. In fact, the micro-tears are safely generated by applying small to moderate force for long periods of time. Applying a small force for long periods of time (4-6 hours a day), is the correct way to create the micro-tears and go about penis stretching. It’s also the best way to ensure safety and prevent injury.
"Some men are confused (or rather not as educated on the matter) and they believe that the outside skin get’s longer and thicker. That’s false. However, some men have false expectations; they think using a penis pump once will cause them to have a bigger penis permanently, and that’s false. As in the gym example before, you have to keep at it, and you have to practice to see results. Yes, early on you will see results like any newbie in the gym, but if you don’t keep at it you will see those results diminish,” says Dubois.
Dermal fat grafting (DFG) involves the extraction of a patch of skin from the patient's own body (usually the lower back, lower abdomen, or buttocks) along with a layer of fat. After the skin is removed from the penis, the extracted tissue is grafted in its place. Because the extracted skin is thicker, it will increase the circumference of the penis. By taking tissue from the patient's own body, the risk of rejection is low.
However, after more than a century of generally dubious and sometimes lunatic penis enlargement attempts, there's still not much you can do. Sure, there are lots and lots of supposed options out there -- penis pills, creams, brutal stretching exercises, horrific-looking devices, and penis surgery. Almost none of it works. The few approaches that can work often have modest benefits and serious side effects. How serious? In some cases, erectile dysfunction-serious.
