The bottom line
Many men believe that increasing the size of their penises will make them a better lover or make them more attractive. But chances are your penis is within the typical size range.
Even if your penis is smaller than average, it may not matter to your partner. There's also no proven way to make a penis larger.
The solution to your concerns about penis size may be as easy as talking with your partner or getting in shape. If those steps don't help, try talking with a professional counselor about your concerns.
