Does size really matter?

What's up with all the penis news lately? First, there was the unfortunately born with a penis on his back baby (someone I know cracked, "He'll give great piggyback rides someday!" har har).

Then there was Buzzfeed's very popular "Authentic Women's Penis Size Preference Chart," (left).

Now everyone is talking about this site, The Condom Monologues, and the Penis Size Chart data (below) from Lifestyles:

"The study found that the average penis length was 14.9 cm (5.9 in) and the average circumference being 12.6 cm (5.0 in)- see chart below. 401 college students volunteered to be measured during 2001 Spring Break in Cancún, Mexico, of which 300 gained an erection to be clinically measured (without pharmacological aid). The 300 effective measurements makes this study double the size of any prior study that uses medical staff to measure penis size."







Sadly, by comparing these two very important charts, you can see that once again, fantasy and reality do not go hand in hand. Do you have an ideal when it comes to size? Does it even make a difference?
