Hello, I have been tested for all stds twice, and both times results came back negative. Now I am experiencing itching around my anus, and I have these cluster of bumps that I thought were hair bumps, so I removed all the hair from them and now they are releasing a clear fluid. I am very scared I have never experienced something of this nature, and I was just tested again for all studs Monday before these bumps appeared. What could this be?
