Hi I'm 13. Even though I know it's bad i have had sex, but I used protection. A day or two after sex my vagiana has been itching a lot. My vagiana has been itching for the past few days so i took medication for it two days ago. The itching hasn't stopped so i used vagasil even afterwards my vagiana still itches really bad and when I applied vagasil it started to burn. I'm not sure if the burning is the vagasil cleaning what ever i have or if it shouldn't be burning. So what do I do to stop the itching and get rid of what I have? I really hope I dont have an std but please tell me if there is a chance i do i'm very scared & don't know what to do! :(
