Daughter Spies on Parents' Lovemaking

A grandparent is upset that his granddaughter is spying on her parents' lovemaking.
12 year old girl watching parents sex play--> confront father
The grandfather should have told the son first. If he didn't seem to care; I would let the performance anxiety of knowing his daughter is watching take place and let nature preclude his sex, and thus his wife's sex. The daughter-in-law must be an exhibitionist to knowingly allow her 12 year old daughter to watch.
