Jelqing is a penis stretching exercise that involves massaging and stretching the penis tissues to create "micro-tears" that supposedly make the penis look longer or thicker. The idea behind jelqing is that manually stretching the penis can create micro-tears in the skin tissue, which will heal and make the penis larger. However, there is no scientific evidence to support that jelqing works. In fact, in some cases, jelqing may actually cause damage to the penis, so it is not recommended. Some risks of jelqing include pain, soreness, and bruising on the penis, as well as possible skin irritation and permanent damage that causes erectile dysfunction. Therefore, it is important to be cautious and avoid doing the exercise if it is painful or uncomfortable. It is also important to note that jelqing is not a scientifically proven technique at this time, and there is no official standardized process for how to do it.
