Im freaking out!

Okay i know its not a big deal but hear me out guys. Me and my bf were having sex earlier today. We always throw away our trash, and we only used 1 condom (we had 2 lying on the couch next to us just in case). We couldn’t find the 2nd one! We looked under the couch and between the cushions but nothing! So wtf happened to it? I didn’t touch it and neither did my bf! We’re freaking out cuz i live with my parents and what if they find it?! Wtf happened?!!😰
