This reminds me of a TL;DR video of a fish species where the female will simply accept a mate she see having had success mating, as it signals the male has been "veted".

Problem is, how does a male fish get started if it hasen't fucked a female fish?

Well two male fishes will pair up to mate in front of the females, who then accept getting fucked by them

This woman is dumber than a fish and likely collecting STDs.
