Comment on Anon has a very specific goal

  There’s a window of time in early childhood (up to about the age of 6) where, if raised with other kids, such individuals will develop a repulsion at the idea of having sex with each other. It happens with siblings, but it can also happen with people we’re unrelated to - just growing up in the same household. It’s called the Westermark Effect.

  If anon wants a chance at this, his best bet would be to find twins that were raised apart from each other. Quite a tall order.

    Love how Westermark decided this was the effect he wanted to put his name on

  Worse, twincest creates much more congenital abnormalities. In this case they’re both the same sex so it doesn’t matter really.

    twincest cannot cause more abnormalities than “regular” (gross) sibling incest. If a set of twins are of diferent sex they are not identical, ie they come from different sperm and different egg. Same as any sibling pair

      Almost… What you’re saying is only true for fraternal or dizygotic twins. It’s possible for a fertilized egg to divide in a way that it separates and both cells grow into twins, these are called monozygotic twins. Now, usually monozygotic twins are usually of the same gender but, there can be mutations. And even in those, the chance of both being fertile is rarer, because of the chance that the mutations usually are X0 leading to Turner’s syndrome in the female child.

  how’s it incest if there’s no chance of procreation?

  source

  • Lumidaub@feddit.org ⁨2⁩ ⁨hours⁩ ago

    Incest is just “sex between close relatives”. Procreation isn’t necessary.

    (In this and similar cases I wouldn’t see an issue with it, btw. If they’re having fun, who am I to judge?)

        Well incest bad also because it tends to ruin families regardless of gender. Most of the time it resolves around an older sibling taking advantage of a younger child and has the power dynamics of any other type of pedophillia

        Even when it’s equitable and between adults people’s psychology treats sexual partners differently. Introducing sexual relationship dynamics : potential jealouslies, the desire of siblings to grow apart and the secrecy pressures of keeping their relationship secret can up the risks of siblings hating each other.

        That’s no law, that’s just the definition. Laws concerning incest differ from country to country but afaik they usually involve penis in vagina penetration (because of, frankly, outdated definitions of “sex”) so twin sisters could go at it if they like.
