TheMarriageGap
The marriage gap is when people are expected to control their sex drives and practice abstinence from when they hit puberty until when they can get married.
People are hitting puberty younger and younger these days, and the time when they can get married is getting older and older. It used to be that people married in their teenaged? years when they were considered grown-ups?. But people today prudently wait until they are finished school (like college or university) before they get married. This means that people can be 26 before they have sex, having hit puberty 14 years earlier.
Most people consider 14 years far too long to go without sex. To be honest, we grown-ups don't know what you should do. Maybe just distract yourself or masturbate.
