On the week of our 20th anniversary my wife, Kat, and I officially became swingers. We met a couple we first spoke to online for dinner, and went back to their place for a foursome that went late into the night. On the drive home, we sat in stunned silence interrupted by laugher; as what we did that night felt unreal. We were liberated by the sexual freedom and adventure we shared; yet what we did went against everything society had taught us about what marriage is. When I asked Kat how she felt about what we had done, she looked me in the eye and said that she felt no shame and had no regrets.
