We first must overcome the fact that we do not become sexually attracted to those we spent our early childhood with, so if you imagine a sister who was seperated at birth.

Now we must overcome the reason for this sibling non-attraction; the fact that genetic diversity is the goal of a species and individual. Close relatives having children can cause concentration of harmfull mutations, and increases the susceptability of the group to parasites. It's this fact that has caused the incest laws to be created. Of course in our modern world sex is not used for procreation. Sex is becoming as much a hobby as hiking, or stamp collecting. You do it because you enjoy it, and actively look to prevent the actual act of conception.

So if you imagine that you are reunited with a sister that you were seperated from at a very early age, and you both consented - if you used effective contraception, would it be wrong to have sex? (And if it's crossed your mind, No, i have never committed incest, and i do not plan to.This is purely thought related)

I dont think its wrong. If you wanna have sex with your sister, be my guest, i just wish i had a sister now ^_^
