I used to use PSP all the time for porn. I only used PS3 for porn once, and that was because my girlfriend had never watched it and wanted to try it. I said, "What kind do you want to watch?" Immediately, and with no hesitation, she blurted out, "Midgets."
I learned something about her that day. I also learned a lot more than I expected about the anatomy of a vertically-challenged person.
