Intersexuality occurs whenever a human being has both male and female physical characteristics. Contrary to myth, intersexuals do not have two sets of genitals; they often have ambiguous genital structures not readily identifiable as clitoris/penis or labia/scrotum, but this is not necessarily true, and intersex people have sometimes gone for long periods of their lives without knowing that they were intersex. They may have gonads of mixed ovarian tissue, testicular and ovarian. They may have unusual chromosomes, for example a mosaic of XX and XY cells throughout the body.

B: I'm intersexual, not a man or a woman.
A: You mean, like a chick with a dick?
B: That's a nice idea, but no.
A: So what have you got?
B: If it's ever your business to know, I'll let you know.
A: Hey, c'mon, I'm serious.
B: So am I.
