Your daughter's developing sexuality and her self-perception is at stake. How she relates to her sexuality now will lay the foundation for how she values herself in future relationships with men. Also, her self-respect rests upon how she perceives she is treated by others. If she chooses to sexualize a relationship, it is important that it be a positive experience that increases her sense of value rather than decreases it. Emotional health and self-esteem hinge upon meaningful relationships with others, whether they are sexualized or not.
Sex can alter the definition of an existing relationship.
It is a big step that requires responsibility for another person. Help her to anticipate these changes and evaluate how she might feel about having sex with someone, after the fact. Use this as an opportunity to connect and discuss sex with your teen, rather than avoid it. Your teenager's sexual development and interest can also bring up vulnerability for you, too. If so, sort through your feelings with your husband or a close friend, so that you can speak openly with your daughter.
