Wet dreams are when a person orgasms involuntarily while they are sleeping because of a dream, which may or may not be erotic. They are called wet dreams because when a male has this type of dream, he may awaken with wet clothing or bedding. This is because semen, the fluid containing sperm, is released during ejaculation. Some people believe that wet dreams will reduce a man’s sperm count. However, wet dreams are a way for the testicles to remove older sperm and help with the natural formation of new, healthy sperm in the body. 😉
