Loving both genders, female and male, is the possible outcome of having lived past lifes as man and as a woman.

So, for instance, one, let her call Jane, had lived as a woman, then lived as a man and eventually became woman again. (could also be man)

A friend of mine declared that topic precisely to me as I asked her how come she was bisexual when she had lived as a woman in her past life.

Intriguing, I must admitt.
