I am a 22 year old college student.  I have been in a monogomous relationship with my girlfriend for 1,1/2 years.  5 days ago I noticed I had 12-15 pin head sized bumps on the shaft of my penis.  I noticed them on a night after having sex with my girfriend.  They aren't painful, they aren't red, they aren't sensitive.  You would never be able to see them if I didn't point them out to you, you have to stretch the skin to get a good look. I have had eczema for many years now, and over the summer it was diagnosed on my testicals, and developed a skin tag down there, perhaps from the eczema.  Lately I was seeing this dry skin develop on my penis.  I had never had it there before, but these super tiny bumps developed where the skin was dryest.  They havent changed, spread, or become open wounds at all.  I went to a tanning booth a day ago, which I shouldnt have done cause it made the area a little sensitive, but in the uv light I got to see all the dry skin around my entire penis.  I tried using elidel on the area, but after the tanning, I think it was too sensitive.  So i simply applied neosporing over last night, and there is absolutely no redness around my penis.  The bumps are still there, but are even less visible then before.  They are slightly raised, but barely enough you can feel it when the skin is stretched.  I have always had itching in my genitals, and doctors have always told me its from my eczema.  I have another very similar looking bump on the back of my penis about 1/4 inch below the head that has been there for months, and developed in a spot that itches frequently.  But this also doesnt hurt, isnt red, or sensitive, its just kinda there, and has been for a long time.  Now that winter is coming, my skin tends to get worse, so Im hoping that is what is happening.  Im just really worried, but I wouldnt know where herpes would have come from since my gf is on the pill and gets pap smears twice a year, and she has never complained.  Maybe these are tiny cysts, or another bumps from moderate eczema.  But if its herpes I just dont know what i will do with myself.  I have read in many of your other posts that if you to stretch the skin, you're looking to hard.  But I am just a worrier, I dont have any other symptoms such as pain in abdominals, flu like symptoms, or tingling or pain.  I just need some help.
Thanks
