Is it just a societal politeness to pretend there’s an incest taboo between cousins?

YUCK, I obviously DO NOT want to fuck my cousin! However, he used to watch the Blurred Lines music video (unrated version obv) when we were preteens and I would watch him watching it and it made me diamond hard.

Scientifically speaking, it’s possible God only programmed anti-incest-ness between opposite gender family members. That would explain why so many gay couples look like siblings.

Or maybe the fact that he was biracial meant my primate brain didn’t register him as a family member. I remember wondering whether his tip was pink like mine or not—maybe that curiosity eventually metastasized into eroticism (many such cases??).

There’s ENTIRE ethnic groups where most people do cousin marriages, right? There can’t actually be a biological taboo. I don’t want to fuck my cousin btw, he went full fundie Mormon and is married with two kids so… yeah…
