I don't think it's a bad idea, but one that could be executed quite poorly. As others have said, if your game-plan is to make sure everyone ICly knows your character is a hermaphrodite, that is more than likely not going to be well received. Play it subtly, and it could work, and even if no one figures it out, it might give you some extra enjoyment playing out that particular aspect. At best, if would give your character more interesting and unique internal monologues. At worst, it would be about as superficial as saying "my character has two sets of ears!"
That being said, I find that more often than not people take certain "quirks" of their character and play it so hard, there is literally no character past said quirk. "Oh, my character is totally gay xD" or "My character is just always really mad about being an ex-slave!" Not that these are bad things, but when they are constantly turned up to 11 and always at the center of that person's RP, things become dull, and quickly. If you think you can avoid that trap, then go for it. If you cannot envision your character outside of being a hermaphrodite, then perhaps it would be wise to rethink things.
