Welcome back to the Forum.  We administratively close posts following two weeks or after three responses in order to manage what would otherwise be a huge backlog of questions.  Happy to address your new questions.

The symptoms you describe are more suggestive of a fungal groin infection ("jock itch") than any STI including herpes. This part of the body is typically moist and chaffing may occur there- this in turn leads to more moisture and intensification of the associated groin odors.  You are doing the right thing to keep the area clean and dry but baby powder may not help. I would suggest an over the counter anti-fungal powder instead.  This is not at all suggestive of herpes (although I can understand how internet based descriptions might make this mistake)- I have never seen HSV in this location and had you gotten herpes from the events you describe, you would have developed lesions within 14 days of your exposures.  (also, even if your partner had active HSV at the time of your exposures, we estimate your risk of infection would still statistically be less than 1 in 1000 exposures).

Your anal symptoms are likewise not suggestive of STI but, particularly at the rectum, STIs can often be asymptomatic or only have mild, non-specific symptoms.  This is while testing following an exposure such as yours is important.

Hope these responses are helpful.  EWH 

Thanks for your response Dr. Hook.  Unfortunately I had to reschedule my testing until next week.  The rash problem in both groin areas has basically gone, fairly faint outline remnants remain, skin has healed very well, not really any flaking, so hopefully as you say it wasn’t a mild herpes event.  I thought jock itch rashes which I’ve not had took along time to heal. The anal area has been fine. As posted, the person licked/rimmed whatever it’s called this area for awhile nothing else.  It’s now been over 5 weeks since the event, will be over 6 by time of testing.  Just wondering whether a person can request the hiv test you described or do some jurisdictions use their own regardless?  I’m having concerns regarding ngu.  I’d never heard of it.  Is it part of chlamydia and/or gonorrhea?  Is it an std, can it occur otherwise?  Should I test for this also?  You are right as you mentioned a couple weeks back, testing info will help as I work through this; I also think unshared very distant past events not dealt with need to be worked through also.  

As I said, you need tot worry about herpes as a cause of your groin rash.  Give up on that idea!  Same with respect to your receipt of rimming.

At this time virtually any HIV test result will provide you with reliable results which, I am confident, will show that you did not get HIV from the events you describe above. 

Nothing you have describes suggests NGU.  Your mention however suggests that you are wasting your time by trolling the internet looking for possible STIs.  If you are doing this, this is a really bad idea which will only heighten what already sounds like inappropriate anxiety and likely mislead you.  No need for testing specifically for NGU.  EWH
