A lot of research suggest that the average length of an erect penis is between 5.1 Inches and 5.5 inches.
When it comes to sex, penis size really doesn’t matter. It doesn’t affect desirability, function or health. Size only matters as much as you let it. Worrying about size can drain confidence and affect your ability to enjoy sex. Furthermore, stress and anxiety can make it more difficult to get an erection or climax.
