A Secret Revealed in a Whisper

I've been married for 20 years, and everything seemed perfect. But last week, during our anniversary dinner, I found myself suggesting to my wife that we try out some new toys and positions from an adult store near us. She agreed hesitantly, but I couldn't help feeling like a fraud as I laid out the items on the bed. We did it once, but now I feel ashamed and unsure of what this means for our long-term relationship.
