Abstinence means different things to different people.
On this page abstinence refers primarily to not having vaginal intercourse - where the penis enters the vagina. Some people will use other kinds of touching to satisfy their needs. Others will avoid any kind of touching because it is too tempting. Some people have intervals of intercourse and then later change their minds and decide they would like to return to abstinence for a period of time. The decision to have sex is your decision, each and every time.
