Nothing is perfect, but if you look with some sort of attentiveness you'll find that imperfections can be beautiful too. I don't like men, so I can't say I have a perfect size, except for my own, which sounds corny, but it's true because that's the only size I have and can't do anything about it.
This thread reminds me of an old thread at measurection.com where one "woman" or troll, quoted the 8 x 6 ideal, and the place was hit all over the place with shit after it hit the fan, it was almost comedic, one troll disrupting what a handful of girls been telling these guys since forever, of course these "the sky is falling" guys had micro penises, or where around 4 inches, so they where hung up about it. And, in here this thread is an ego buster.
I don't really know what I'm trying to say, except that not being the ideal sucks for both genders, specially when the perceived ideal is within a minority.
