Over 2 years sometimes i get thick vaginal discharge which looks a bit yellowish/green, has a bad smell and is at times itchy. i am 17 and am a virgin?

Virgins can get: vaginal infections. Two of the most common vaginal infections are NOT transmitted by sex. Rather they're a result of an imbalance in the normal vaginal environment. Some women just by nature have more vaginal secretions than others. Since you're so young etc., it's best that a doctor exam you and test the discharge next time it flairs up. Best wishes. Dr. Anne
