Okay so I took a shower earlier today and shaved down there and later around 8 I noticed down there was itchy so I itched. I had no reason to think anything was wrong (I have very dry skin) and it just kept being itchy so I looked and noticed my left labia minora was swollen and red so I ran to the bathroom and put cold water on it to try to decrease the swelling. I am only 15 years old, I'm not a virgin but have had sex recently so it's not an std or anything similar to that. Please help me I'm scared!
