I'm just saying there are two separate taboos here. Child sexuality and incest. And one made plausible does not create a direct bridge to the other. So I still don't get why you seemed to explain the pairing plausibility, in fiction, through proving child precociousness and sexuality.

ALSO. Why does child-sexuality have to exist for their to be incest? Most of the incest pairings I've seen have been between two consenting adults. So...I don't know, dude! I'm still confused. I'll read this again in a little bit, after I've had some coffee.
