As long as he isn’t Incest, everything’s fine (づ￣ ³￣)づ
Um no as long as there isn't rape it's fine. Consensual sex has never bothered me and I don't know why it bothers anyone else.
Incest is morally wrong, not only that, if a baby is produced, He would have a higher chance of gaining the parents genetic illnesses, although it wasn’t present in his/ her parens
In short, the product of a incestuous relationship may suffer and the parents would be at fault for this
