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?

I have a cousin who witnessed the same thing when she was 4 LOL I think some children have better memories than others and so it depends. She related the story to a few of us, her close cousins. We of course had a good laugh but agreed that it can also happen to anyone of us(:
