This is the single most misinterpreted fact about men that women cannot seem to wrap their heads around, because sex for women is totally opposite.

Most women would never even dream of sleeping with a majority of the different men in their lives and are way more discerning when it comes down to who they will actually sleep with.

This category is exponentially smaller than the first category. Where a man might be open to having sex with 200 women, he may be open to actually dating three.

These are the women who he actually enjoys spending time with, who he finds both physically attractive and mentally stimulating. These are the women who he wants to bring to his office Christmas party, who he can see bringing home to meet his parents, who he wants to explore the world with and make reservations at the cool new restaurant down the street with.

If you are a woman who is actually looking for a relationship, these three words will help you discern: close thy legs.

If you are single and want to be in a committed relationship, make it a new rule that you will stop engaging in casual sex with guys who you are dating casually.
