What does bisexual mean? I can assume that homosexual stands for having a sexual desire for the same sex, heterosexual for the opposite sex, does this mean bisexual stands for having a sexual desire for both sexes?

Don't homosexual people end up with one sex? For example, a gay man will end up with another man....or a gay woman will end up with another gay woman. And heterosexually speaking, a man and a woman will end up together. So, how can we classify bisexual into that category? If someone is bisexual, who will they end up with? A man, a woman or both?

I don't believe bisexual can really be compared to hetero/homo sexual classification. To me, bisexual seems more like a lifestyle choice that normally doesn't last. Is it an in between stage? What is bisexual in your eyes?
