Seriously?
I take it that you understand the difference between being intersex and hermaphroditism.
You do realize that a human hermaphrodite is medically impossible. A true hermaphrodite requires that not only are both types of gonadal tissue present, but that both the testes and ovaries are functional. To date, while the literature is littered with pseudohermaphrodism where one type of the gonadal tissue is functional and the individual expresses both male and female external genitalia, this does not really count as a hermaphrodite.
Now, from a porn perspective, if you are asking if anyone has been with an individual who phenotypically appears to be a hermaphrodite, that is, has the external structures concomitant with both sexes, that is a different story.
