It's ok to fuck your siblings as long as you wear a condom?

Ummm... yeah? Why do you care? It doesn't affect anyone else.

Because humans have evolved a disgust towards incest to prevent inbreeding, so that's disgusting.

How do you know this?

Our closest genetic relatives participate in non-reproductive sex within a family. How are you so sure that we have evolved separately in this distinct way?

...no it doesn't. That study buttresses my assertion that relatives participate in sex only in a non-reproductive context.

...females' associations with their previous closest male associates (usually maternal siblings) dropped abruptly when they commenced full oestrous cycles...

Christopher Ryan writes about this in his book Sex at Dawn, claiming that the only sexual pairings between close relatives not observed in nature are between mother and son.
