It is helpful for older teens to understand and admire the ideal of sexual integrity. Call them to greatness, while also setting down clear guidelines of what is and isn’t permitted in their opposite-sex friendships while they are under your care. We advise parents to initiate advanced conversations with both sons and daughters about how sexual desire is tricky to control, but absolutely manageable with time-tested strategies. Teens should also be taught about the dangers—and avoidability—of STDs, and encouraged to show compassion and empathy towards peers who don’t know how to live sexual integrity. Finally, let your teens know that you have great confidence in their ability to live out sexual integrity and practice true love and authentic friendship. But even if they make a mistake, they can always make amends, rectify, and start again.
