Young people need to know that abstinence is a far more complex, difficult concept than it is often portrayed. Abstinence is a decision about sexual behaviors that a person may make throughout his or her life. It is a choice made at a specific time in a specific situation, for a specific period of time, whether one is in a partnered relationship or not.
