A couple were married for 20 years

A couple were married for 20 years. Everytime they had sex the husband would insist the lights to be turned of. The wife was getting bored of the same thing everytime. So that night when they were having sex the wife turned on the lights and saw her husband with a dildo in his hand. The wife very annoyed by now, started shouting at her husband and asked him to explin himself. The husband replied with "Explain our Kids."
