I'm kind of freaking out right now - when I was showering, I noticed a weird pimple behind my labia minora (left lip). Out of curiosity, I touched it a bit; when I did it felt kind of painful. I don't know where it came from - I haven't had sex before and I don't have or share any toys with anyone. I'm kind of afraid to tell my parents in case they think I've had sex, since I've had quite a strict upbringing and they constantly nag me not to. Can someone help me?
