Abstinence is the practice of refraining from sexual activity, which includes vaginal, oral, and anal sex. It is the only form of birth control that is 100% effective in preventing pregnancy and also protects against sexually transmitted infections (STIs). Abstinence can mean different things to different people, and some may choose to practice abstinence only on certain days or with certain partners. It can be used as a method of birth control by keeping semen away from the vagina, preventing sperm cells from reaching an egg and causing pregnancy. Abstinence can be practiced by anyone, regardless of age, gender, sexuality, or previous sexual experiences. It can be chosen for various reasons, such as personal, moral, or religious beliefs, focusing on work or school, or waiting for a special partner or marriage. Abstinence can be successful when practiced diligently and with planning within relationships. It is important to communicate with partners about what abstinence means to each other and to be honest about reasons for choosing abstinence.
