So i've been doing a little noticing

And i've noticed that countries that have a long history of eating visually disgusting things typically have girls who have a lower aversion to oral sex.

I think this is because, mentally - subconsciously a PENIS is no different from fried while fish on a stick, or stinky squid thats been left out all day, and if you eat that stuff then dicks are not a big deal, even if they smell kind of weird sometimes.

tldr; higher disgust tolerance for PENISes if you already eat gross sea animals or duck fetuses etc.
