Waterfowl are the best-known example of antagonistic genital coevolution in vertebrates. Males have corkscrew penises and penis length is correlated with the frequency of forced extrapair copulations (FEPCs) among species. FEPCs are costly to females, and they detract from otherwise female autonomous precopulatory mate preference. Females have evolved convoluted vaginas that make it difficult for unwanted males to evert their penis fully inside the female when they coerce a mating
FEPCs can be up to 40% of all observed copulations

This is the future of humans: normies will evolve corkscrew dicks to rape and inseminate roasties before Chad can.

Did you know most birds don’t have penises?
