A senior in high school who is following Christ should be able to articulate the why behind purity and have an understanding of why we choose obedience. There is a good chance that any senior who is not walking closely with the Lord has had sex before (or is currently in a sexually active relationship). It is also possible that a protege could have a child by the time he or she is a senior. Talk to your protege about sex, marriage, and relationships like he or she is an adult.
–If your protege is dating, get to know his or her significant other. Make sure to ask direct questions about the relationships
–Continue to speak about marriage and invite your protege into yours (if you are married). Since many of these kids have never seen a good marriage, they must see it modeled as an actual reality
