Your sexual intercourse must not be imposed without your clear permission. It's important to feel free in your choices, and always be able to say no.
The decisions you make now will affect your sexual health at adulthood. Your desire to affirm your femininity or virility is important, but must not make you forget the precautions to take to protect you from the dangers to your health. Diseases, sexually transmitted infections, unwanted pregnancies, HIV transmission, drug abuse and/or alcohol... take care of you!
