For a lot of women, maintaining their mystery is especially difficult because when they find a good man they want to do whatever they can to keep him. They become easily accessible, sexually available, and completely open. In the end, even a great guy with good intentions can lose interest in a woman who’s too open and too available. Why? Because to him, she has no more mystery left to her since she revealed too much of herself too quickly. He may feel cheated out of a challenge and your value may actually drop in his eyes.
