You describe the symptoms of a cold, not an STD. I'm not sure about the skin changes on your penis, but it doesn't sound at all like herpes. More important, 2 doctors have examined you and reassured you. (I'm not sure why you went to the second, having been given such strong reassurance by the first.) Herpes does not cause "spots" that persist unchaning over a couple of weeks. Herpes only causes sores that develop over a few days, scab over, then heal within 10-14 days.
1) I doubt you have herpes or any other STD.
2,3) The urinary discomfort probably isn't related to your sexual exposure in December. If/when urethral STD symptoms appear, it's generally within 2-3 weeks. But chlamydia might be a slight possibility. But probably not herpes.
4) Complex epidemiology. Obviously there are some settings in which HSV transmission is more efficient than in the monogamous couples selected for the research study.
5) Variation in color of a skin lesion is not a symptom of herpes.
I cannot guarantee you don't have an HSV-2 infection, because a quarter of the population has it. You could be tested if you wish. But if you do, it has nothing to do with any of the problems you describe. A positive test would mean you have asymptomatic genital herpes plus something else causing these other issues. But of course follow up with further visits to you doctors if you remain concerned.
Good luck-- HHH, MD
I should also add that the doctor seemed to think the slight urethra sensation was probably a UTI due to the consistent sensation (not only when I urinated).
Last follow up - I promise (i'm extremely anxious) from a statistical point, my girlfriend and I had unprotected sex probably about 5 times in all. I also got tested a year ago for everything and was fine. Thanks so much
UTI is rare in healthy young men, so that doesn't seem likely. Otherwise the additional information doesn't change my opinion or advice.
Thank you very much for your response. I got tested for HSV2 yestereday. I'm praying it is negative. This is a wonderful site, and I'll definitely make a donation. Thank you so much again Doctor.
