I am worried about my penis. It is only 4 inches when erect. Will I be able to please my partner?

Contrary to popular belief, the length of the penis has nothing to do with performance. While average erect lengths of the penis are between 5-7 inches, it is normal to have sizes smaller than that. Men usually think more about having a larger penis than women want in a man. Most studies reveal that penis size is much lower down the list of a woman’s priorities in a man.
