Earwigs

You aren't half the man this earwig is. And by that, we mean earwigs have two dicks.
Though some species only have one and are mocked horribly at earwig urinals, the ones with two tend to have a preference in use, meaning they're either right weinered or left weinered.
Because the earwig's wang is delicate like fine china, if it snaps off they just switch over to the other one and go about their business. So far, scientists are unable to tell if a right weinered earwig that has to use his left shoots off with all the girly-throwing power you'd expect.
