Thanks for posting your query at DoctorSpring.com. Firstly, my apologies for the exceptional delay with the reply.
I can understand your concern. This doesn't seem to be herpes. It is seen as a cluster of fluid filled blisters. The spot seems to be a friction dermatitis or a bacterial infection. The picture is not clear enough.
I would recommend that you mix and apply neosporin cream and cortisone cream twice a day for two weeks. If it doesn't revolve then I would recommend that you see your dermatologist.
Hope this helps, I would be glad to answer any queries.

It is definitely that, because it still looks the same but looks to be healing up with no pain, I can send you a picture if you would like, but I definitely don;t think it's an STD 100% Thanks for your answer. Please let me know.
