I have no scientific proof to back this up, but I think there is something inate in us which makes us not be able to fall romantically in love with a sibling. We're just made that way, our brain psychology normally doesn't work that way. I'm not talking about siblings who didn't know they were siblings; in those cases they don't feel/see each other as brother and sister. But the ones who were raised together, well I don't think I've ever heard of a case where they fell into romantic love and wanted to get married/have kids together. Incest happens all the time in this world, where brothers/sisters/fathers impregnate each other, but that's not from love, it's from pure sex and lust.
I don't think it's innate...I think we don't think of our siblings that way because it's so far from the cultural norm.
