Hello medical staff, I was wondering what my potential risks are from these last few sexual encounters. All of these encounters were done at massage parlors with some functioning as sex workers. My last exposure was unprotected oral around 2 weeks ago (4/1/25), my exposure prior to that was protected oral and vaginal sex (3/23/25 - 3/24/25), and my exposure before then was near the end of February. I just can't seem to convince myself 100% that I haven't caught anything. I am also worried because these were done under discretion and I have a girlfriend that I don't want to risk giving anything to. In addition, around 2.5 weeks ago I got a rash on my groin near the dorsal side of the base of my penis that wasn't really painful, but a bit tender to the touch and had maybe 4 to 5 bumps on it that were nor pus filled or water filled to my knowledge and did not arrive in a cluster. This rash I noticed maybe a day or two before my bout of unprotected oral. I used some antifungal cream on it and it began to recover a day or two after applying the topical, and I went to my PCP where I showed him the before and after of using the cream to which he told me that it's very likely fungal and just jock itch and prescribed me a different antifungal with steroids to help with it. 10 days after constant application and the rash is almost gone. My questions would just be: 1) Do I have to paranoid that the rash was anything more than fungal in this case? The fact that there were bumps and that I didn't really notice if they were water filled blisters is really making me doubt if I just overlooked it? 2) Was I at risk for anything from these last three sexual encounters? (I am especially paranoid of herpes) 3) Would it be safe to assume I'm clean and continue having unprotected sex with my girlfriend? Also, had two full STD (blood and urine) tests since the 4/1 exposure, all negative. Thank you!

Also I have not had any other symptoms (besides the rash if can even be considered a symptom) such as discharge, lesions or sores (again assuming the rash was not that), nor burning urination.

Welcome to the Forum.  Thanks for your questions and your implied confidence in our service.  I'll be glad to comment.  As a generalization, the comments you describe were relatively low risk- most commercial sex workers do not have STIs, you used condoms for your vaginal exposures and receipt of oral sex is relatively low risk.  In addition, most single exposures to any infected person is unlikely to transmit the infection (assuming that the exposures you describe were with different partners.  The absence of symptoms other than the rash you describe and your negative tests effectively rule out STIs ( if your rash were syphilis, your syphilis blood test would have been positive.  ---

Yes, sorry for not specifying on the tests, I had a syphilis AB igg, HIV 1+2 AB + HIV 1 p24 Ag qualitative immunoassay, serum, hepatitis C virus Ab, serum, chlamydia + gonorrhea RNA, QL, HBsAg, serum, trichomonas vaginalis RNA, tma, genital, and HSV2 and 1 igg Ab inhibition, serum or plasma done.

Also I've had like a dull, but not really noticeable aching and kind of irritable sensitivity? On my pelvis and urethra, I don't know if these are just psychosomatic symptoms and I'm over monitoring myself, but is that also something to consider? And some very slight burning sensations when I urinate after not drinking as much water as I usually do (so when my urine is like yellow or darker so anything but close to clear)

That's a lot of tests- I hope they were not too expensive.  FYI, hepatitis C and hepatitis B are so rare that there is no medical reason for testing and HSV antibody tests this son after an exposure are of little use.  I urge you to stop testing and move forward.  ---

Thank you again, you telling me to move forward is helping. I'll just use the testing to ease my anxiety. The testing was not expensive, thankfully, but also thank you for your concern in that regard!

I realize I'm beating a dead horse here, but just hearing your opinions and what you have to say to all these people on these forum is especially reassuring to me given your expertise. Thank you again.

Oh, and when will HSV antibody tests be conclusive?

Final responses. ---
