Welcome to the forum and thanks for your question. However, I'm not sure I can help very much. You're essentially asking me to mediate between conflicting professional opinions, which no online expert can do.
That said, your description doesn't sound at all like genital herpes. And of course of all penile skin conditions, herpes is a lot less common than several others. Any number of dermatologic conditions could be responsible and I will be very surprised if the PCR or culture (the swab test from the lesions) is positive for HSV. My view is that you should have followed the internist's advice to see a dermatologist. Most likely a dermatologist would be able to instantaneously make an accurate diagnosis based on simple visual inspection.
To your specific questions:
1) None of your symptoms is typical for a new HSV infection, and the timing also isn't right. Although new herpes can show up as late as 10-14 days after exposure, usually it's 2-5 days.
2) Oral sex never transmits HSV-2. HSV-1 could be so acquired; but as noted above, I doubt you have herpes of either type.
3) I'm not going to speculate on an unlikely outcome. If it turns out you have HSV, despite all the atypical features, we can address the prognosis for future recurrences at that time.
4) If your penile lesions are still present and more or less unchanged in appearance at this time -- which I gather is a week or more after they appeared -- that alone will prove it isn't herpes. In that case, go ahead and see a dermatologist and take it from there. If herpes then seems likely, and assuming the PCR or culture (swab test) and blood test are negative, then the next step would be another HSV blood test in a few weeks, to see if it has become positive. But as should already be clear, I doubt it will come to that.
For the time being, you should go forward with the assumption that you have something other than herpes.

I didn't really understand the reference to HCV testing--my derm occasionally makes very odd statements about improbable scenarios which I have learned to ignore over the years. While I am a gay man, I don't have unprotected anal sex (or even that much anal sex at all), don't engage in fisting or anything like that, and have never used injection drugs so it seemed like an outlandish suggestion. Nevertheless, I figure at my next annual physical exam I will mention it to my PCP and let him decide but it sounds like you are saying it isn't necessary and you are the ID doc. Again thanks for all your help.
I was thinking of mentioning lichen planus, but don't like to speculate too far about likely non STD causes. LP is among the most common genital skin rashes.
I don't understand the advice about HCV testing or why it's in the picture here. You and/or your dermatologist may be among the many who have come to misuderstand HCV as a sexually transmitted infection. In fact, heterosexual transmission of the virus has never been clearly documented and appears to be rare. The only proved sexual transmission scenario for HCV is for traumatic (often bloody) sexual practices (e.g. fisting) among men having sex with men.
Anyway, glad to hear of the good news outcome.
Hi Dr. Handsfield,
As you predicted, both the blood test and PCR test came back negative. My PCP referred me to the dermatologist in the same medical group who examined it and assured me that it was not herpes but lichen planus. He decided to biopsy for confirmation and stated that if confirmed by biopsy, I should get an HCV test as a precautionary measure. After reading about lichen planus online it sounds very common, almost always benign, and usually totally unrelated to HCV which comes as a relief.
Thanks for this forum. It has saved me money and worries on many occasions! Best Wishes from Chicago.
