Great question! Just because your genitals are maturing and becoming more adult-like does not mean you need to use your body parts for sexual activities. Deciding to have a sexual relationship requires smart decision-making skills and mature conversations about consent with another person. Many young people realize the responsibility behind this decision and decide to make sure they are more prepared when they reach a certain age. Talking with a trusted caregiver can help a person figure out what is best for them.
