I found out that my parents are having while i sleep, how should i react to the fact?

It's human nature. I wouldn't want my child to be awake while I was having . At all. Plus it's human nature to have . I understand it might disgust you now, but what do you expect them to do? After having a child, never have again? It's human nature, either they jack a lot or they have . You might want to laugh everytime you see them now, but how do you think you were created? A stork?
