How can u improve penis length and width?

Too long short wide?: Any size is fine. Other than babies with penis birth defects, pubertal boys with hormonal deficiencies, or rare cases of under-development, treatment to change one's penis length or width is not necessary. For adult males, a penis with a firm erection is large enough if the penis touches the sides of the other person's opening, which is a vagina in the vast majority of cases.

Bigger penis: If you are very obese, weight loss can give you length back but nothing can make what you already have bigger.
