It’s both.

It’s an evolutionary arms race, female ducks have clockwise spiraling vaginas with false pockets to stop male ducks who have counter clockwise corkscrew penises.

That sounds like a bad way to ensure the survival of your offspring?

and a giant duck penis starts chasing you? You need a gun

so it's suicide?

because if it's a giant duck penis you might need a rocket launcher. or autocannon.
