Cindy and Alicia, both seventeen, walked out of the mall after a fun afternoon of shopping. Just as they reached Cindy’s car in the parking lot, two young men drove by on motorcycles. One of them knew Cindy from school, so they stopped to talk.

After a few minutes of casual chatter, one of the young men asked Alicia if she’d like a ride on his bike.

“No,” she said, laughing. “My dad would kill me if he knew I was riding on a motorcycle.”

“Ah, come on,” he teased. “You’re a big girl and no one’s gonna know. I’ll just take you around the mall one time.”

Cindy joined in, urging her friend to have some fun. Alicia finally relented, and swung up on the back of the bike. Pressing up against the young man, she held on tightly as he twisted the throttle and roared away.

That’s when three neurochemicals took over Alicia’s mind and body.

Dopamine, the reward hormone, had kicked in the moment she saw the young man looking at her. Now it increased, bathing her in a wave of pleasure. “Cute guy. Seems to like me. Great body. This is so much fun!”

When Alicia pressed her body against his and felt his skin touch hers, a burst of oxytocin was released into her blood stream. This is the bonding hormone. It creates feelings of trust, safety, commitment, exclusivity. “Could this be the guy I’ve been dreaming about all my life?”

As the motorcycle picked up speed, made a few sharp turns and popped a wheelie, she screamed as a third neurochemical infused her body: adrenalin. The fight-flight hormone. It’s triggered when we sense risk or danger. It increases our heart and respiratory rate, tightens our muscles, and prepares us for intense physical action.

Like gasoline on a fire, it also magnifies the effects of the other two neurochemicals that were flooding Alicia’s body. “Wow, I’ve never felt this excited before!”

In the time it took to circle the mall, Alicia’s mind had been reprogrammed. “This is it. He’s the one. The guy I’ve always dreamed about. He makes me feel so good. I’ve got to see him again!”

That night as she tossed sleepless in bed, she built a fantasy future around this stranger. The more she thought about him, the more convinced she was that she couldn’t live without him.

But the next morning Cindy called. “Hey, Alicia. You know that guy you met yesterday? Stay clear of him. I found out he was kicked out of school for doing drugs. He’s had a whole string of girlfriends, two of whom got pregnant. He can’t hold a job, and he beat up one of his closest friends a few weeks ago. He’s bad news, babe, so stay away from him.”

Alicia was shocked as fantasy collided with reality. Reality said, “He’s bad and he’s dangerous, and I need to stay clear.” Fantasy, fueled by dopamine, oxytocin, adrenalin and the deceitfulness of our sinful nature, said, “That can’t be true; he was so nice to me. And even if it was true, he’d never be like that with me. I just know with us it will be different.”

Fantasy won out, so the cycle began. Endless texting. Phone calls. Secret meetings. Exciting touches and increasing intimacy. Guilt. Shame. Arguments. Another girl. Jealousy. Fights. Abuse … and then he was gone, leaving Alicia bruised and traumatized, both physically and emotionally.

We all know an Alicia. She may be your daughter, or the daughter of a friend or relative. Maybe it’s a teen in your youth group. Alicias are everywhere.

And most of them know virtually nothing about the three neurochemicals that can hijack their brains within seconds of meeting a cute guy … just as similar hormones can hijack a young man.

You can change this. You can help to educate the teens in your life, so they understand the marvelous complexity as well as the dangerous potential of the neurochemicals and hormones that impact their thinking, emotions and life-changing decisions.

How? Give them a copy of a book entitled, Hooked: New Science on How Casual Sex is Affecting Our Children, by Joe McIlhaney and Freda McKissic Bush, both of whom are medical doctors.

This book is written entirely from a medical perspective. It describes the design and dynamics of our neural and hormonal systems in simple language that a teen can understand. It also contains numerous testimonies from teens who describe the emotional pain caused by casual intimacy:

“I wish I had said no. I wish I had been strong enough, and I wish my parents had helped me more. I had no idea that being intimate would change my life so much.” Karen, 20

Although both of the authors are Christians, the book contains no Bible quotations or references, so it can be used in any setting. Even so, the principles they teach line up squarely with biblical morality. Over and over again this book echoes the simplest principle of physical and sexual engagement: “Do not awaken love until it is ready” (Song of Solomon).

Having worked with many families whose teens were entangled in physical intimacy, I strongly recommend this book as a resource that could save your children and your family from much trauma and pain. You could read this with your teens, assign it as summer reading or read and discuss in your church youth group, Christian school or home school co-op.

To strengthen your teens one step further against the deceitfulness of pleasure hormones and cultural pressure, encourage them to through our Discovering Relational Wisdom course individually, with your family or in their church or school. In addition to strengthening their emotional intelligence, empathy and impulse control, they can earn a “Certificate in Enhanced Emotional Intelligence,” which will prepare them for college and give them an advantage over their peers as they compete for scholarships and top jobs after graduation (see Emotional Intelligence for College and Beyond).

A small investment in these resources can help your teens navigate the landmines of adolescence and move into mature, disciplined and joyful adult life.

Reflection Questions:

• Why do teens who know all of the right Bible verses still give in to our culture’s pressure to be sexually active?
• Why does simply telling teens it’s wrong  or sinful to engage in premarital intimacy fail to deter them?
• What are some of the ramifications of casual intimacy among teens?
• How is the promiscuous activity of Christian teens (and adults) impacting the witness of the church?
