Oh, double standards. Men have sex: no big deal. Women have sex: they get scorned, shunned, exiled, or willingly run over by a train. Women in literature have been getting punished for their lustful ways practically since the dawn of time (see: Adam and Eve).
Most of the men in the following books are never punished for engaging in relationships deemed socially inappropriate. Some do experience personal setbacks, but none are shunned publicly in the way that their female counterparts are.
While some of the women’s sexuality does not directly lead them to their untimely, unfortunate demises, we think that, had they not had these “sexual indiscretions,” they might have fared better in their books.
