I am a 20 year old male, and I have never had intercourse, but about a week ago, I had the opportunity to perform oral sex and I went ahead and did so. I felt a little nervous afterwards about the possibility of getting an std from the experience, even though the person told me they were clean. After a few days I began to have pure liquid diarrhea, and it has gone on for about 4 days now. I m going crazy looking online and seeing diarrhea as a first symptom of HIV, it is giving me really bad anxiety, but it seems like for an accurate test I have to wait until 3 months after exposure. I m just in a panic, and I want some peace of mind, what should I do? Part of me thinks the diarrhea might be due to my stress about this, is this likely?
