Question: Yesterday I discovered several red bumps on my penis (two or three isolated ones and then several so close together in a line it looks like a scratch. I'm still not positive it isn't) in the area between the head and the shaft. They are very tiny, not much bigger that a period. There is absolutely no pain, tingling or itching present; if there was even a hint of it I know I would blow it out of proportion, being the slightly hypochondriac person that I am. I also can' t see any kind of breakage in the skin or evidence of them being filled with fluid. I have no evidence of a fever, cold or swollen lymph nodes.
I have been with my current partner about 3 months. Prior to her I had been tested for everything (to include hsv1) and came back negative on all accounts. She also claims to have been tested and I have no reason to believe she is misleading me.
About 36 hours before I noticed the bumps we had very vigorous and extended sex (oral and penetrative). In that time I also switched shower gels and wore two pairs of brand-new underwear. Would this more likely be either a friction burn or dermatitis from new fabric dye/new soap, or could it possibly be herpes?
Also seeing that I tested negative for HSV1, if this was in fact primary herpes shouldn't I expect it to be a more noticeable case since I would have no antibodies in my system? Or does it not work that way? I've read some outbreaks can be so minor they are easily missed...
Thanks for your help!
I should also mention that they responded VERY favorably to neosporin and some cortisone cream.

That's actually the clearest I can get...I only have a cellphone camera and they are small and seem to be fading rapidly. If they disappear completely within a day or so (existing for a total of 3 or so days) can I safely assume it is not herpes? A primary outbreak should last a minimum of a week correct? Still totally painless and have transitions from red to a pink/flesh color without any oozing/crusting
