Can you have intercourse with your daughter?

Answer 1

It is physically possible to have sexual intercourse with your daughter, but if you do you are committing incest. If your daughter is not an adult, you would also be committing statutory rape and child abuse.

Answer 2

That would be incest and very much illegal, in many countries also as adults. And yes, you can. There are many sad cases where the father has impregnated his daughter. He ends up in prison for many years.
