"Uh, book," I said slowly, an idea forming in my head, "Could you show me the stats for dicks size across different demographics?"
I was about to clarify what I meant, but, before I could continue, the text on the page faded away, and new words came into focus. This time, instead of just stats, the book had charts and figured.
"Damn, you really are like a textbook..." I muttered, leaning over to peer at the page.
The book showed all kinds of demographics, each with a line graph showing frequency of dick sizes among that group. At the top, and least interesting to me, was gender. The male category looked about how I expected, with a peak around 8 inches, and visible up to around 15 — fuck, all the way to 15 now — but, to my surprise, the line for women wasn't entirely flat.
"I guess according to the book trans women count as female...neat," I muttered to myself, then moved on.
Below gender were various categories for race. It didn't vary as much as you'd expect. If I squinted I guess I could say that the chart for black guys peaked a little higher than the one for white guys, but the average was around the same. I reddened a bit, and tried to ignore the fact that I was a little disappointed. I guess it makes sense that porn exaggerates stereotypes. Still, if I was mad about it I guess I could change it...
The charts for race went on for a while, but most of them looked the same. Below that was one for age, which I paused and looked at for a while. The line was pretty flat up until around 12 to 14 — puberty? — and it kept rising at a slower but steady rate until around 21. That could be interesting to mess with...
The page ended after that, but, when I turned the page, I saw that the charts went on. There were tens of options — height, eye color, base body type, even ones for different sexualities. I didn't see anything like body weight or social class, but I guessed it didn't make much sense for biology to vary based on non-genetic things. None of the categories were different enough to be interesting on their own, but the possibilities were endless.
