ive bin waking up to severe itching at the inner part of my vagina, i also ive bin having alot of yellow discharge which smells, and makes me feel really umcomfortable. i started to rub it because the itching is so bad and i think i may of cause an irratation and it started to swell around the inner part of my vagina, and burns when i pee. im just seventeen years old, i had sex twice in my whole life, and both times were unprotected. can anyone tell me what they think may be wrong? please help me.
