My wife caught me masturbating to our sex tape?

Many years ago, my then girlfriend, now wife and I made a sex tape. Over the years, I have used this tape many times to get off when sex was not immediately available.

Today, my wife caught me spanking it to this tape. She didn’t directly acknowledge the tape even though it was blasted on our bedroom TV. My question….should I bring this up? Or do we pretend it never happened? My wife did not in any way seem upset by what she walked in on.

Edit: Thank you all for the wonderful perspective. I was feeling like a weirdo and sexual deviant when I posted this morning.

I will definitely be showing my wife this thread when she gets back from her work trip and will request a third tape since the ones I have are quite old – from 2008 and 2009 respectively.
