The size of the erect penis has been studied across the world in various studies, because as a question it continues to arise in the minds of men. An average of around five inches has emerged often, but it is important to note that size discussions among men are given to exaggeration.
Apart from the fact that size itself does not matter as much as men think it does, this exaggeration ends up creating a rather unnecessary anxiety in the minds of men. This anxiety has led to a proliferation in the number of "solutions" to increase size including pills, gels, oils and creams even though there are no clinically proven non-surgical methods to increase size!
