Masculinity vs Femininty

There are many types of traits and reasons that may take the responsibility for a person being "too" masculine or "too" feminine. We recently wrote a gender analysis paper and the views expressed in class were relatively important and interesting, but true. For example, a woman is talking to her friend "normally" and when a man comes around, she tends to talk in a high pitched tone. This is a typically true situation, but why does this happen? Why are we held to society's view of a "woman" or a "man"? We are liberated to our own choices and views but yet, we choose to think about what others are thinking about us. This is why our generation, if we don't do anything, and other generations, are being messed up. SOCIETY! What is really normal? We've learned that genders are not based on the biological make-up anymore (male vs female) but rather has multiple categories (based on masculinity and femininity). This gives society basis to categorize people easily. I know that the term metro sexual is used widely now, but why? Society wants to have a hold on a well-kept man saying he's a little closer to the "gay" side rather than the "straight" side. But these men are interested in woman as much as they're interested in their hygiene! Society has a hold to our minds and we need to gently push away from its views. Don't worry I can go days on this subject but I wanted to provide a small synopsis of the subject so others can elaborate.
