Incest

Someone on /b/ keeps claiming that we have genes that prevent us from being attacted to our siblings. How true is this? I for example find my sister extremely hot. I masturbate to her pictures all the time and would fuck her without a though given the chance.

Uhm, you are denying that the Westermarck effect exists?

If you are serious, here:

From the abstract:
[...] The Westermarck Effect hypothesis that early childhood co-socialization leads to a lack of sexual interest at maturity is thus supported for female participants but not for male participants. These results are consistent with expectations from parental investment theory that females should show greater inbreeding-avoidance than males do because of the greater costs females suffer as a consequence of inbreeding depression.
