It's so the male duck can scrape the semen of any previous partners out of the female duck's vagina. This was a random mutation that somehow became dominant because it perpetuated the species. Unlike leaving all that semen in there, which ... wouldn't ... have?
Remember, sexual selection favors traits that benefit the carrier, being able to have a mate exclusively bear their offspring and excluding competitors would favor their genes, unlike the mate potentially bearing offspring from multiple contributors (even within a single clutch, but I’m not sure about that part, not a biologist)
I don't get it. (Update: Now I get it, but I wish that I could go back to the way things were before I found out.)
Duck penis
Duck dicks are corkscrew shaped
And duck vaginas are also corkscrew shaped, but they spiral the opposite way.
It's like you wanted to be cursed.

What did I JUST tell you about knowledge
Kk that took me a minute. And yeah... Yikes lol
I wish I didn't know now what I didn't know then.
If you knew then what you know now you'd have better coping skills probably... Or not. Who cares honestly.
Some knowledge is cursed. There are things we're not supposed to know.

Even when it benefits the species as a whole. Nature always was shortsighted, and the cause of all our suffering.
