QuestionI am 22 years old. My penis is 2.5 inches when erected and 1.25 inches when relaxed. My height measures 5.8 inches. I have a lot of hairs on my chest, legs, and genitals. Will my penis grow? What should I do to get it elongated?
From your description of yourself, you have reached your full adult size. While there are numerous quacks ready to promise you anything for a chance at the money in you wallet, none will provide what you are looking for -- a longer penis. The length of your penis is determined by the genes you received from your parents. Nothing that you eat, drink or do to your body will make it any bigger.
However, since you didn't mention your weight, if you are overweight, your penis will appear smaller since the base is hidden inside your body. Losing excess weight can make the penis look longer by more of its actual length to be seen.
Even if extra weight is not the problem, a small penis doesn't mean you can't enjoy sex with your wife or have children.
