So my first question is why haven't you had a doctor check it out in person? Really, the only way to know for sure if it's herpes is to have a doctor culture it. The sooner you can get in, the better, because as soon as things start to heal, it's harder to get an accurate result. Make sure they do a type specific herpes culture.
You could also ask to get a type specific IgG blood test.
This may be herpes, it may be something fungal, like jock itch, or something else entirely. Genital hsv1 looks and acts exactly like hsv2, though you probably wouldn't have as many outbreaks, but everyone is different. Most people find a herpes outbreak at least uncomfortable, though some are more painful than others.
Honestly, it doesn't sound like herpes, but it definitely sounds like something a doctor should see.
