The world is full of jerks of both genders. Game is irrelevant. Man or woman, if you're laying down with someone you just met, you have severe self-esteem issues.
When it comes down to it, we are all responsible for ourselves. You are only a piece of meat if you conduct yourself like one. And you are only a notch on someone's belt if you allow yourself to become one.
Have a little self-respect and use a little common sense, and you won't be a victim of anybody's "game".
