Sounds like boils to me. Herpes looks like blisters. Boils in the groin area are common--thighs, etc. They are of no significance and rarely need any treatment at all.
I guess I'd have to hedge and say that unless somebody looks at it (or a good-quality photo at least), they couldn't give you a definitive diagnosis, but if it "fits the discription of a boil perfectly," it probably is just a boil.
Best.
