Question: I have a sixteen-year-old female friend who came to me for help. She was masturbating for the second time, and she thinks she had an orgasm, when her nipples and vulva changed from a pinkish color to a redder color. I am a guy and I don't know what to tell her. Can you help me?

Answer: Please read the article about Sexual Arousal and Orgasm, there I describe the physical indications of sexual arousal and orgasm.
