I guess someone has to add input to this thread since you went into the effort of making it lol.

As the old saying goes, "use it before you loose it"

shrug best I can come up with.

All i can figure out is that you'd think that this would be a result of testosterone.  But because of things like bodyfat, environmental estrogens, aging, and so forth some of the test we make is converted to estrogen and basically thrown away.  But i can't find any studies on google for penis size unfortunately.
