Not sure what you mean by "too much of a woman". They could be implying that you are too dominant and therefore out of sync with the average male, or perhaps you are simply dating guys that are not on the same wavelength as you. Or maybe you are unusually attractive and that could be intimidating to men who do not feel as attractive as you.
Here is another hint - talking a lot can make you the centre of attention and therefore popular in a group of people, but men hate it one on one with a woman.
I would suggest that true charisma is something like a radio frequency - everyone around them starts to vibrate in sync.
