Masculinity and femininity

I feel like such things do not exist. Both of these are just words that contain a few attributes that someone put there. I mean if you did stopped and thought for yourself what is which of them, in what conclusion would you go ? You can't say for example, masculine is more energetic, because you have seen energetic females, neither for being more aggressive , or more loving. Both of these belong to both.

Now what you can say is that masculinity and femininity isn't related to the gender as we know it. But if so than why tf did we choose these words to name that group of attributes? Such labeling has made a mess over hundred and thousands of years, when one should obey to a set of attributes that belong to his gender.

So besides my idea, one question I would ask is that : is there an inherent type of attribute or behaviour that belong to one gender, non dependent in the fact of wether they embrace it or surpress it?
