Honest reason for a condom in laundry??

Anna

So I found half a condom in our laundry. No wrapper. We've been married 4 years and have a 6 month old daughter. I have zero reason (other than this) to think he would cheat. We spend every single evening/night together. He works with only 4 other men for his family's company. I don't see how he would even have time
