When you get sick you get horny?

This has happened to me twice in the last 4 years. I have tried to find an answer on the web but so far I have failed. SO THIS IS MY THEORY. When you are sick and your life is threatened the body responds to increase your chances of reproducing and continuing your species. I was sooooo horny I could not believe it. I felt like I was dying and I could not get out of bed for more than five minutes but I HAD to masturbate(I am single) every two hours or less. This could not have helped my recovery but I absolutely HAD TO DO IT. I was fifty years old at the time and have never felt so aroused. Even when I was in my teens I never felt so much urge. Does anyone out here agree? Medical experts please respond.
