I'd say it's coincidental; although I have a slightly different point to make concerning the size of your hands vs. your penis: My hands are not particularly long; when compared to a girl I know(her hands, that is...), hers were perhaps slightly longer, but my hands were significantly wider.
My penis has a more prominent girth than length.
Coincident?
By the way, the length of my penis is also about the same as the length of my hand, but it depends on where I define the starting point of my palm to be(not to mention the starting point of my penis...). |
