You know this is written by a woman when...
One of the female characters admits to sleeping with hundreds of men and her fiancé still stays with her. Fantasy. Any man with options is long gone with that revelation. The woman is damaged goods.
Also the scene where two guys go down on the girl at the same time AFTER both have had their penises inside of her. Yeah, that's never going to happen unless the guys are bi. Must be a female fantasy.
