Would a couple have sex on top of their newborn child? Whether the child is in the womb or out of the womb, it is still their child. It is utterly degenerated that people have sex with a child in the womb; the child is undeniably aware of it and overwhelmed by the lust of the parents. That is another way people spread their degeneration to their children: right from the womb.
