Your Definition
There are two definitions used in different contexts: (In singing) 1. A muscle in your lower chest under your lungs. Many singers and theater kids know this definition due to how often it is mentioned by singing teachers. You can feel yourself use it most whenever you are about to sleep or whenever you are breathing without thinking. (In sex/contraceptives) 2. A round disk inserted into a vagina to prevent sperm from reaching the egg and getting a woman pregnant. It is about 88% effective due to improper use. It is best used with spermicide. Very few women chose to use diaphragms because of their lower efficacy as well as the need to see a doctor to get one.
