So first, no this doesn't sound like herpes. You wouldn't have all these symptoms for so long without having any blisters.
Herpes infects nerve groups, and genital herpes infects the sacral ganglia. This means you can get outbreaks anywhere in the boxer shorts area. You could get outbreaks in the urethra if you wore a condom, but I'm told that is PAINFUL.
Your symptoms sound more like prostatitis. Have they done a urine test where they look for white blood cells in your urine? Have they talked about a prostate exam?
You don't mention your age, which is fine and you don't need to, but men of any age can get prostatitis. It can be bacterial, sometimes from an STD, or not. The older you are the better your chances of things like BPH.
It could also be a hyper-awareness of your body if you are feeling anxious about this for any reason.
