Size Musing

Biologically speaking, most men when it comes to penis size fall into the average size category, somewhere between 5-6 inches in length. Roughly 15% of men worldwide are of the above average size, between 7-10 inches in length, and 5% are in the mega size, greater than 10 inches. Now saying all that, have you ever noticed that the vast majority of shemales are of the above average or mega size categories? Considering that most guys always want to have a bigger penis because women always say that they want the biggest cocks, why do you suppose that guys who are so well endowed would ultimately become shemales, many ultimately fully transitioning to full female and removing their cock? This is a rather new thing to happen in society, and seems to be most prevalent within the Hispanic community. Thoughts on any aspect of this are welcome.
