There's a fallacy that many people have bought into without realising it:

"Men and women are polar opposites."

Its not true.

Most of a man is very similar to most of a woman.

There are more similarities physiologically, than there are dissimilarities.

There are more similarities psychologically, than there are dissimilarities.

And here is the biggie:

There are more similarities hormonally, than there are dissimilarities.

The opposite sex are not exotic aliens that are impossible to understand.
