They’re a secondary sexual characteristic, so it seems like something that would get attention.

    Mature women is straightforward, older = more knowledge and capable.

    Pretty much everything else you listed is about trust, so I’d say that trust is a very big thing you value in a partner, and due to humans very long time they spend dependant on parents and our community survival strategy, trust is very much a trait that is selected for.

    People that are untrustworthy are unattractive, a lot of kinks primarily build on top of publicly shameful acts in private, which is effectively the ultimate trust fall exercise.

    Feeling like you can trust a partner with such acts is very very positively reinforced genetically, so it becomes sexually attractive.

    In short: because humans live together and make complex communities, trust is important, which means getting kinky is very sexy as it signals deep rooted trust.

      Okay, fine, but what about non-hetero attraction and relationships? There’s an entire spectrum of human attraction and sexuality. I know there was an old study about a genetic factor that would increase the likelihood of, in this case, a male being attracted to other males, but I am confused as to how a germline could propagate a heritable factor that would result in no offspring. I am not an expert.
