I do believe I have brought up this point already, but in my stories, the female is always 16 or so. I just so happen to think of that age group being prime for the types of stories I write.
I must also bring up another point: I would never hit a girl, I would, however, hit a male that hits a girl. Now I have walked a fine line between reality and fiction. I remember back in my...Sophomore year, was it? There was a girl that lived across the field from my house. She was absolutely beautiful-gorgeous face, huge breasts, cute feet...and for a time, I daydreamed of sneaking into her house and tickling her and all this stuff. I had no intention of ACTUALLY doing it, but that didn't stop me from planning every aspect. Hypothetically, I probably could've accomplished such a task, without even being caught. But morally, that was much too far across the line for me to even consider on a realistic level. It was always fantasy. I think perhaps that's another, more subtle aspect of what sirthumper is saying. Back when I used to do things like that, thinking of what would be done to this girl was arousing, but then thinking about the actual task of getting into her house and neutralizing her also added to the sexuality surrounding the situation. The above might have sounded quite...disturbing to some people, but keep in mind that I was a horny high school male who didn't have a girlfriend. Once I got a girlfriend and determined that sex wasn't as great as it seemed, I stopped with the creepy kind of daydreaming and turned to just thinking of plots for my stories.
