tiny red blisters on rim of penis

i had unprotected sex with my girlfriend twice in two days. after the second time, immediatly there was a lesion close to the head of my penis.  i got this tested and it went away and they said it was just caused by friction.  so i thought my troubles were gone when i started having pain a couple days later towards the head of my penis.  I noticed tiny red blisters basically covering the rim of the head of my penis.  my family doctor said it was a male yeast infection.  I am circumsized. i went through a couple of creams such as over the counter lamisil and perscription ketoconazole.  These did absolutely nothing so he sent me to a urologist.  The urologist also thought it was a male yeast infection and i took dyflucan 100mg for 21 days while i also followed a decent candida diet.  There was no progress to be shown.  I also found later that my girlfriend had a yeast infection.  It is now 4 or 5 months later.  Everytime i have an erection there is pain and i've notice tiny slits almost like papercuts on occasions.  I have recently been to the dermatologist and she says she doesnt think its a yeast infection but she thinks it could be eczema.  She is having me put vaseline on my penis for 3 weeks and covering it with gazz wrap to try to heal it.. my family does have a history of eczema and i do have a slight case of it on my arms during the winter...

now for my questions:
Is it possible i had a yeast infection and got rid of it and now its just irratated/eczema/allergic reaction now?
do you believe using a candida diet helps fight a yeast infection if i even have one?
would masterbation (masturbation) effect it at all?
any other possibilites of what this could be?
anything to avoid when attempting to get rid of this?
if u had to make a guess.. what do u think it is?

i am uncircumsized and i have the same thing. one exception, when i pull my foreskin down there is white stuff that resembles tissue paper that is rolled when wet. my gf has been reported to have yeast infection. i washed really well and make sure i am dry. i do this often. there is no foul smell. just tiny micro cuts. around 20 of them.
