And contrary to popular belief, a lot of women are not into a really big guy because it can be uncomfortable. It really is more of a guys trying to impress other guys thing. As you may already know, the ancient Greeks thought a small penis was ideal (you'll notice that on many statues).

Rewind to the ancient Greek world of around 400 BC, and you’ll find that large, erect penises were not considered desirable, nor were they a sign of power or strength. In his play The Clouds (c. 419–423 BC), ancient Greek playwright Aristophanes summed up the ideal traits of his male peers as “a gleaming chest, bright skin, broad shoulders, tiny tongue, strong buttocks, and a little prick.”

Historian Paul Chrystal has also conducted research into this ancient ideal. “The small penis was consonant with Greek ideals of male beauty,” he writes in his book In Bed with the Ancient Greeks(2016). “It was a badge of the highest culture and a paragon of civilization.”
