Evolution tends to select against that. It's why we dont asexually reproduce clones of ourselves over and over. Its why we have males and females instead of being self fertilizing hermaphrodites.
There os nothing inherently morally wrong with it (because morality doesn't exist) but from even a purely physics/biological lens it's just counterproductive and ineffective.
>>82973917 (OP) >How are fathers with hot daughters not sexually attracted to them
im sure some are. Imagine your wife gives birth to a teen version of your wife. That'd mess with your head
This is why stepdads are inherently flawed. If you didn't go through >>82973932 and then you have stepdaughter who is in her prime there is no way you won't be attracted
