@cell@pl.ebin.zone @kaia@brotka.st there's an effect that it's more likely for a man to become gay depending how many other sons his mother has had before, so a third son is much more likely to be gay than a first son. I read an interesting theory that this might be because the growing baby is essentially a foreign object in the mother's body and there's a delicately balanced fight between the immune system of mother and child. And just like with bacteria, viruses or parasites, the mother's immune system becomes better at 'fighting' the child after the first, so later sons become more feminized by the mother's system. But now I read that there's a similar effect for lesbians so sadly this neat theory doesn't seem to be true.
