Is a biual nymphomaniac any different from a heteroual or gay nymphomaniac?

From what I read about nymphomaniacs, they are so hyperual and ually promiscuous, that they become "genderqueer" and do not care with whom they have with. This is in the case of a monoual nymphomaniac, so would it be any different from a nymphomaniac? Does the nymphomania act on a different realm than one's sexual orientation?
