* a special advantage or immunity or benefit not enjoyed by all
* prerogative: a right reserved exclusively by a particular person or group (especially a hereditary or official right); “suffrage was the prerogative of white adult males”
*A privilege–etymologically “private law” or law relating to a specific individual–is a special right or immunity granted by a government to a restricted group, either by birth or on a conditional basis

So, I don’t think sex is a privilege (its a basic human attribute), but I really like this discussion that you’re having. It is so important to talk to teenagers about everything you’re talking about! And while concern about one’s own physical, sexual, emotional health is critical, so is concern for the other person’s physical, sexual, and emotional health.

I really love the Third Mindfulness Training by Thich Nhat Hanh:

The Third Training: “Aware of the suffering caused by sexual misconduct, I vow to cultivate responsibility and learn ways to protect the safety and integrity of individuals, couples, families and society. I am determined not to engage in sexual relations without love and a long-term commitment. To preserve the happiness of myself and others, I am determined to respect my commitments and the commitments of others. I will do everything in my power to protect children from sexual abuse and to prevent couples and families from being broken by sexual misconduct.”

Although I think that sexual intimacy without love and a long-term commitment can be just fine, staying mindful to potential future suffering can help to hold one back from impulsive behaviors.
