Hi there Troy. Apologies am not Dr Rohit but decided to answer as you have been awaiting a reply for awhile & are understandably anxious. At the outset, your rash does not appear to be any standard manifestation of any STD. it is more likely to be some non-specific irritant dermatitis or a fungal infection. Use a standard antifungal-steroid cream locally & it should clear up in a day. A standard antihistamine tablet preferably a non-sedative one should be easily available from your local chemist. Hope this helps. Cheers & All the best. Dont worry if the two of you have been safe hitherto, there is very little need for fear albeit i empathise with your anxiety. hope have managed to calm those nerves!
