Hi, I am a 17 year old female who is sexually active. Last time I had sex was yesterday and now my vagina itches a lot. I did shave right before having sex, though. There is pain at the bottom of my vagina (sorry, I don t know the correct terms). Regardless of the pain, the itching is what s keeping me tonight. What is the severe itching and pain? And how can I stop it?!!!?
