Everyone has secrets, but often in relationships, men tend to hide things from their girlfriends or wives? Why? Simple!

The Super Hero Complex - we want the women we date to feel like we are invincible. We want them to feel like we always "save the day" and can rescue them from anything. But, if a woman we were dating knew that we spend too much, drink too much or spend too much time online, she wouldn't want to be with us and more importantly, she wouldn't want to have sex with us.

The Mystery Man Syndrome - we'll answer only the questions we're asked because divulging any "extra" information would go against the "mystery man" persona that we're trying to achieve with the women we date. Women are suckers for mysterious men. The allure is too great for them to resist, so if a woman we were dating knew everything little thing about us and every little secret we had, it would kill the mystery, man.

Boys Cry, Men Don't - Letting a woman in on our secrets requires us to be vulnerable. This is something most men are not good at, so to avoid being put in a touchy-feely position, we will simply not let you in until we feel we can trust you with our secrets. That, unfortunately, takes many, many years. -- The Average Guy
