Interesting. It could be because women don't want to be thought of as 'roots', and you are simply irresistible to men.
However, you also suggest that even of the men who want you, that they only want your arse. I am sure they do appreciate you for your top personality and effervescent joie de vivre as well but hey, men are men and clearly if they are ass-men, they are going to want your rear assets. Sorry.
Having said that, it sounds like you might have had a dose of what a lot of women endure? Most women resent being chased for their below-the-belt assets and wish more men would get to know their razor-sharp wit.
Perhaps you could find such women and discuss these matters?
