About two or three weeks ago, a red rash appeared on my penis. I didn't think too much about it, because it didn't have any pain or itching, and I had just become sexually active (with my girlfriend) for the first time. I passed it off as friction/irritation because it is was only on the outside edges of the base of my shaft. I didn't stop masturbating and having sex.
Fastfoward a few days, The rash became very dry and began to crack. It also looked very raised.
Fastfoward about a week, two small (1cm) red circles appeared halfway up my shaft. I get worried and make an appointment with my healthcare provider, who said it did not look like herpes at all, stating it looked more fungal. I was prescribed a cream called Naftin and instructed to use once a day.
Fastfoward another five days, I've been using the cream, and it hasn't made much progress. It now includes a series of red dots on my pubic area just above my penis. The rash on the left side base of my shaft is now hardened and painful, with one singular yellow blister in the center. At first glance, I assumed that because it was dry and blistering that it was healing. But now I'm worried again.
The only possible contact I've had with any STD is that my girlfriend had a herpes outbreak on her lips a few weeks back. But we avoided all contact during this time and I took many precautions. Other than that, my girlfriend has no STDs that she is aware of, and let's rule out the possibility of cheating.
I've had both my healthcare provider and platoon medic (I'm Army) look at it, and both state that they don't think it's herpetic. Nevertheless, I'm making another appointment to go tomorrow. In the meantime, does anyone have any ideas as to what it might be? I'm pretty much scared ********.
