I'm guessing you have already compared your symptoms to pictures of PPP online. However, self-diagnosis is not reliable and you should definitely be seen by your doctor.
However, Genital Herpes outbreaks generally present with a number of clustered blisters, generally located on the head of shaft of the penis.
Have you ever been tested for GH before? If not, it may be wise to request a type specific IgG blood test when you see your doctor. This should be done soon, while you still have active genital symptoms.
Also, on a final note, do not touch the sore. Leave the area alone. If you rub, prod, and poke the sore it won't heal!
