Why do phans have the primeval urge to have sex with Erik/ The Phantom?

Hi late here but here goes I think the dark mystery of him is what makes him interesting to women,and in a strange way the tragedy of his story and how he basically at the end of a 日 just wants the 爱情 of one single person is what makes him interesting to me, it's also his passionate and intense personality may also be why he is alluring to female fans.
