So I'm 13 years old and a virgin but my crotch smells gross. It also itches alot. A few nights ago I was scratching my self and since it has hurt down there and burns/hurts when anything touches a certain spot. Also when I look at my underwear there is always some white stuff dried onto my underwear. What's wrong with me? I'm getting really worried. Should I tell my mom to take me to the doctor?
