About 10 days ago I had protected vaginal sex with a sex worker. I think she performed oral with no condom for a very short time, then used a condom, but I was a little drunk and don't remember for sure. A condom was definitely used for vaginal penetration. After a few days (really almost immediately) I started to notice some mild burning in the tip on my penis and I think frequent urination. I had no sores or marks (except a puffy spot on my shaft that becomes a hard vein when erect, but I think that is a separate issue), I also began to get chapped lips, and they seemed like normal chapped lips but I have now had them for almost a week. I went to the doctor today and he said that my lips looked like normal chapped lips and not like herpes. I never kissed the girl or performed oral sex. I have had a few mild infections in the past and had them cleared up with antibiotics, but as the years went by it started to seem like every time I had sex with a stranger I got something. That is why I am so nervous now. I am in a relationship so I felt incredibly guilty and anxious beginning the next day and immediately became paranoid that I caught something. It was the only instance out of my relationship in about a year and a half, but I know from past history that these diseases seem to grow on trees these days. How likely is it that I got herpes, and how likely is it that the herpes I got caused my lips to become chapped like they did? I got an STD screen today and will get the results next week, but I am scared to death to sleep with my GF because it would be devastating if I gave it to her, and I feel like if I wear a condom it is suspicious. I have read that it takes a few months to detect it so I will have a hard time not having sex with her by then. Even my doctor asked me if I need meds for anxiety even though I am usually an easygoing person. I can barely sleep I feel so ******. Is the burning all in my head? I even self-medicated with Flagyl and Doxycycline for the past week because my experience has taught me that they clear up several of the common infections I used to get, so I keep that stuff on hand. I read a lot about the power of the mind to create these symptoms, but it seems hard to believe.
