My wife an I are quiet and always have been. Having children in the house ensured we kept it quiet. Especially since the first came 9 months and twelve days after the wedding and the sixth 17 years later.
My wife is in remission from cancer, a two year battle. It has been over a month since her last radiation treatment. She had a hysterectomy last summer because of the cancer. Now I am lucky if we are intimate once every two weeks.
