Intersexed people exist. (Hermaphrodite is considered somewhat offensive) I've met a few before, it's a natural mutation and that's just the way it is for them.
Most intersexed people identify as one sex or the other, and chose to live their lives and modify their bodies to fit that sex and that gender identity.
A childhood friend of mine, who is intersexed, lives and functions as a woman, despite the fact she was born with testes in addition to a vagina. But because she is, ultimately, a woman in all of her life, when she has sex (which she does with men only), it's downright heterosexual. Were she to have sex with a woman, that would be homosexual. But when a man looks at her, sees her body, shaped as a woman's body is, his attraction to her is simply straight.
Similarly, if a man were attracted to an intersexed person resembling a man, then that would be homosexual. Ovaries don't suddenly make it straight when Joe thinks Ted has a sexy ass and a beautiful dick.
Oh, and you don't know the meaning of the word homosexual. Homosexual simply means "sexually attracted solely to members of one's own sex." It doesn't mean, necessarily "physically incapable of straight sex." Some gay people have sex with members of the opposite sex, for various reasons, including denial, cultural pressure, curiosity and in some instances, prostitution. Similarly, some straight people have sex with members of the same sex, for similar reasons. Their sexual orientation, in any case, is determined by their attractions, not the person in their bed.
Dumbass.
