Guess the Sexual Identity

How can you simultaneously have the biological body of a man, identify yourself as female, have sex only with straight men, and not consider yourself gay without contradiction? It turns out this can all be true if you are a Fafanini (not sure about the spelling).

Of course, you don't have to be from Samoa. It is widely known that similar traditions have existed in many different cultures throughout the planet. In the case of some Native American tribes, for instance, there was an extra category: physical women whose gender identity is that of males (or something along those lines; I don't recall the details at the moment). The variety of human practices, beliefs and values truly is remarkable, isn't it?
