Alright, I am in high school, and I have already have 11 sexual partners. By this I mean I had sexual intercourse with them. I used a condom every single time, and most of my partners were either virgins or they had few partners before me. I have never experienced any STD symptoms nor have any of my partners. However, just recently I noticed a strange bump on the inner part of my vagina. I looked up the symptoms and it appears to be an abscess. However, I'm not ruling out the fact that it could be some STD. I want to get tested but that is proving difficult at this time and I was wondering what the chances of me having an STD are?
