But men didn't invent the erotic romance novel. Women did. The vast majority of erotica writers AND readers are female. (http://www.ehow.com/way_5192600_tips-writing-sensual-books.h...)
You are an unusual example of your gender. You must know that.
Maybe the fact that most men prefer the plotless hardcore scenes found on the various you- and -tube sites, and its the women that are writing and reading erotica, is a coincidence.
But I tend to think it does indicate something about a difference in male and female sexuality, innate or otherwise. The fact that you are an exception to the rule doesn't make it true that men, in general, are consuming written erotica.
P.S. Obviously men do write and read some erotica, but even here there are differences. My favorite erotica writer, Morgan Hawke, wrote a blog post about the differences: http://www.darkerotica.net/WhatGuysWant.html
P.P.S. Would you be willing to read the second draft of my first novel, a sci-fi erotica with plot lines around programming? :D
