The only way to really know if this is herpes is to be examined and get a culture (not blood) test. That said, what you describe sounds at the very least, atypical for an initial episode. First of all, you have an alternate explanation (swim suit chaffing). Second, we would expect the initial episode to occur more extensively, to be associated with more discomfort and to potential be accompanied by flu-like symptoms.
As I said before however, the best way to address this and any lingering concerns is to go today to your own health care provider or perhaps the local STD clinic and get an examination and a herpes culture. I hope this helps. EWH
I do plan on getting this checked out immediately now but a couple of questions. Does this sound more like herpes or HPV or molluscum or something different? What would the chances of me getting herpes be from a one-time encounter with someone who didn't have any lesions?
Thank you for your help.
