Many guys are curious how their penis measures up to others
You measure the girth of the penis by folding the tape line around your penis, at the position of greatest girth.
Guys are often concerned about the length of the penis, but for intercourse it’s more important how thick it is. For girth determines the amount of friction between vagina and penis and thus the amount of stimulation.
When it comes to sex there is no ideal girth. It depends on the vagina. There will for instance be not much friction if the penis is thin and the vagina wide, but when the vagina is tight and the penis thick intercourse will be painful. So what really counts is how two lovers match.
The average adult penis girth is probably in between 4,5-5,5 inch. But research results differ.
The biggest increase in penis size is between 11 and 15 years of age. With most guys their penis won’t grow anymore after they turn 17.
