As much as I feel betrayed by my brain, truthfully I wish I were about .25" bigger in both length and girth. It would put me comfortably beyond two numbers that for some reason or another have stuck in my head for years as ideals.
Being the size I am has caused enough problems so I don't have any need for more, but those numbers are just in there.
All in all, I love my size but if I had the chance and no one would know, maybe a smidge more because I'm human.
