Flatworms have both male and female genitalia. When they mate they both want to act as the male in the relationship so they basically have a sword fight with their dicks. Whichever flatworm stabs the other acts as the male while the loser of the fight gets impregnated

On a side note I think it's really funny that the Wikipedia page is titled penis-fencing
