I think you make a lot of sense there, and I was not confused at all by what you have written.
I also like the Kinsey scale model of looking at both hetero/homosexual feelings and dom/switch/sub feelings. That would probably throw a lot more people into the switch category than there are now, if people tended to use a scale.
Personally, I can't really imagine being the top without sort of a nervous, bad feeling. I did try it when asked but I didn't get any fun out of it, and he ended up "escaping" and overpowering me anyway. That part was funI may be about a one on that scale.
Probably I am closer to the middle than the edge on the gay/bi/straight scale, although I have had absolutely no experience with women.
