Hi there -
No need for pics here since we can't diagnose you over the internet, even if we were docs in this forum.
A rash can be so many things, and you should get it checked by a doc.
I'm sorry I can't be more specific, but it really could be herpes, warts, an allergic reaction, dermatitis, etc.
I was planning on hitting the doc if the final confirmation that it is herpes occurs, though until then i dont believe it is. Basically if they become blisters and "pop" forming ulcers i believe is the dead givaway. If it doesnt clear up in 2 or 3 days im gonna go anyway though(had them for about a little over a week).
Herpes doesn't always blister and burst. Some people only get bumps, redness, irritation or itching.
