My 5-year-old daughter caught us having sex. Since then, I have somehow become very paranoid in having sex out of the fear that she will see us again. How do I get this out of my head?

oops....'that' moment...... well, you were upto some mischief and she caught you, but that doesn't mean you stop doing it... just remember to close the door from now on, and yes, do act normal in front of her, not conscious, so that she too forgets about it and moves on with everyday routine as always
