Caught Wife And Now I Learned Something

So I suspected my wife of cheating I don’t know why call it a gut feeling. So after a 3 day weekend the following Monday I drove to work texted my wife I’d be in meetings and wouldn’t be able to text much. I waited a bit left my phone in my desk in case she checked my location and returned home. When I arrived home to a random car in the driveway my suspicions were all but confirmed. I peaked in the living room window and saw no one. I entered as quiet as possible and went down the hallway towards our bedroom peaked around the corner. There she was on top riding some random guy I thought I’d go off in a fit of rage but I just stood quietly and watched I couldn’t take my eyes off. It’s probably the most confusing moment of my life I watched until we made eye contact. I put my finger to my lips to shush her and waited in the spare room until they finished. It was a very awkward conversation after but turns out i like to watch.
