Discuss how pressure should not be part of the equation for your teen or their partner. How does it feel to be pressured into something they don’t want to do? The first time should be a decision based on love and respect for each other. Sex should always be a zero pressure situation.
Emphasize that it is up to them to stick to their limits and tell them to be aware of how far things are going once their hormones are enjoying a make out session.
Explain that a “deal breaker” is something—a behavior, comment, or value—your teen absolutely cannot tolerate and violates his or her trust in someone.
Work with them to create a list of rules together because they will be more likely to follow rules they help create!
There is a wide range of “normal” when it comes to human sexuality and your teen needs to know what the range is so they form happy, healthy relationships.
