Thanks for your question. We know that a person’s sexual attraction can range from being asexual, attracted to females, attracted to males, or a combination of females and males. This attraction may stay constant throughout a person’s life or may change.
In the United States, sexual health of teens is considered confidential unless there’s a safety concern (i.e. if there’s concern for sexual abuse). The specifics of confidentiality can vary by state or region. To be sure, you can ask your therapist before disclosing anything. Consider saying something like, “If I talk to you about sex stuff, will it be confidential?”
