I'm in a monogomous multi-year relationship, and made the mistake, 2 months ago of having protected sex with a sex worker. Over the next weeks I developed a rash in my groin that was painful, red, and itchy that resembled jock itch. I am a heavy male, and sweat in that area. I went to my GP who assured me it wasn't herpes or an STD, and suggested that it was Tinea. I used lotrimin which seemed to help.
Anxiety has worn me down to a nub. My wife is pregnant. In the second month I returned to my GP with slight changes in the rash that he said, "If you don't believe me that it's not herpes - I'll send you to a dermatologist."
I went to the dermatologist - in week 6 after the exposure. (I additionally used Labsafe at 6 weeks to run an HSV-2 IGG blood test in that week which came back negative). He saw slight redness at the tip of my penis, and the rash in the groin. He prescribed a topical steroid, and the rash has gotten worse since application.
At this point - week 8 since exposure - I returned to the same dermotologist who reassured me again the rash didn't resemble herpes or any std. He prescribed another topical steroid to apply to the tip of the penis (focused around the urethra - strictly redness with intermittent stinging pain).
How worried should I be about herpes or any std - given the tests, the protected nature of the exposure. I DO have a painful rash that has come and gone, but have not seen any vesicles with pus, or scabbing etc. I have had some of the peripheral symptoms (fatigue, back pain, etc.) I am worried about my wife and my baby, and wonder if you can give me a sense of what a reasonable mind frame might be for this exposure, and next steps.
