To my way of thinking there are only 2 genders, male and female. Now, this has got nothing to do with bodily functions and appearance. I'm talking about how people think, feel and behave.
Generally women have a better command of language than men, or let's put it a different way round language is more of a feminine attribute.
Navigation, map reading and generally finding where you are, planning a journey is more of a male attribute. These are just two examples of tens of if not hundreds of different attributes that a person can have.
Take the navigation skill, think of a bell graph, a normal man would be in the middle. In other words most men would be where the Bell curve peaks. If you superimposed the female bell curve on there, then this curve would be slightly to the left, more to the feminine side of the graph. You could say less skilled, at navigation, but you could also say it was more feminine. It's more like it's not important to a woman.
Now if we look at the language, we have the same situation two bell curves, a male bell Curve and a female bell Curve. The left side being more female and the right side being more male. It would work equally well the other way around, this is just the way I think about it. I'm also thinking that these two bell curves together remind me of something. If you take the extreme right man/male orientated person not necessarily a man, by by any means, but you have a person that's up and out there Orienteering all over the country, possibly in the army and/or Boy Scouts. This would not interest me in the slightest. So I tend more to the feminine or I'm probably middle of the road really, an average on navigation.
Regarding language, I think I'm a bit more feminine on the slope of the graph, I like language it fascinates me and I'm always making up new words. So what I'm trying to say is, it's not about men, or about women, every person is a combination of these attributes, in different amounts and this applies to anything you can think of. I've just used the example of language and navigation because these are general stereotypes which everybody understands.
