There’s not much evidence that the food you eat can actually change the size of your penis. However, eating a healthy diet can improve blood flow, helping you achieve bigger erections. Losing belly fat can also help your penis look bigger. Stick to a diet rich in fruits, vegetables, and lean proteins. Avoid lots of high-fat foods, like cheese or fatty meat.
Penis pumps and vacuums are popularly used as sexual aids to promote erections in men. They are also used by some with the intent of increasing penis size. These devices are placed over the penis (and sometimes the scrotum) and use suction to engorge the penis with blood. If used consistently over a long period of time, they can cause the skin of the penis to become "spongy" and have a thicker appearance.
Try ginseng. Korean red ginseng is said to give the nervous system a boost through ginsenosides, a natural component of the plant. While there is no conclusive scientific evidence that ginseng causes the penis to get bigger, men who took ginseng extract tablets as part of a study in South Korea experienced better sexual function after taking the supplements for several weeks.
And if you're worrying about your size pleasing your partner, remember that penetration is just one part of sex, and everyone's preferences are different. Many women don't even orgasm from penile-vaginal sex, for instance, and other people don't care very much about size or length. The size of your penis could possibly be unrelated entirely to your partner's ability to experience pleasure.
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.
