My AoA is set in concrete and, in spite of my personal attempts to change it, is solidly in the range of 5 to 9 for only female. Because my attraction is so age, gender, and situation specific, I know that the origin of my pedophilia is environmental/psychological rather than genetic. However, my father, whom I've never met, was 48 and my mother was 15. He was also a bush pilot (uh, aviation, not...)
The world is a rather complicated place and Minor Attracted People come in all sorts of flavors, sexual desires, and attraction origins. What the demographics and statistics would be are probably impossible to know. But, we can guestimate. You're welcome to do so.
Finally, and this is why I am so goddam weird, I don't want to fuck. I have done so in the past and, in fact, have had three kids. But, it's not what I really want to do. Can't pigeonhole that other than to call it weird.
