A recent study of over 500 teenaged same-sex twin pairs suggests there may be a hidden benefit of being a lovesick teen. Teenagers that have sex with a romantic partner engage in fewer delinquent behaviors than do teens that have sex outside of a relationship (i.e., “hooking up”). In other words, teens spending more time with a boyfriend or girlfriend leaves them less time to get into trouble.
