Does size matter?

Is there a connection between the size of your penis and the desire to wear diapers

No. The size of your penis is inversely proportional to the size of your wristwatch.

LOL Intruder, The real answer is yes, If your penis is shorter than your left leg, you may develop a diaper fetish. This was, believe it or not, a nonscientific study based on the revelation that men who had longer penis' were more likely to run around nude just to show it off.
