Shaking your penis. This is another simple and effective method, and perhaps the quickest of them all. Instead of tugging or stretching, just give your penis several gentle shakes. Think of it as "waking your penis up". Just like any other body part that becomes stiff or remains stagnant for long periods of time, we like to shake these parts, wake them up, and in turn they go from stiff to stretched out and elongated. Same thing works for your penis. Shake him out some and not ony does the tissue become stretched, but blood flow will increase some which also creates larger size.
Panic is the anti-answer, so let’s end that now. Like any situation, this one demands some straight up facts, so let’s begin there. The first and most important fact is to forget what you’ve seen in photographs, in movies, or on the web. Based on a sample of 1,661 guys, the average self-reported erect penis length is 5.6 inches. Technically, according to the Mayo Clinic, a penis is not even considered small unless it measures less than three inches when erect.
How Does it Work? There are a few different types of penis enlargement surgery based on different principles and on the desired outcome. One method is to transplant fatty tissues from elsewhere in the body into the shaft of the penis – this can be successful but is described as being “visually odd”, and the results often disappear within a year as the fat is metabolized. Another technique is to disconnect some supporting ligaments. Reports suggest that this can offer a few fractions of an inch in length, but leave the erection pointing down and not up.
Platelet-rich plasma (PRP) has been used clinically in humans since the 1970s, and the healing properties of PRP have been attributed to the secretory proteins and autologous growth factors that may enhance the healing process at a cellular level. It’s also been found to enhance the differentiation, recruitment, and proliferation of cells that are involved in tissue regeneration . Through the years, researchers have found many different uses for PRP, studying it in the skin healing process  and as a symptom- and disease-modifying treatment for osteoarthritis .
