It sounds more like irritation than an STD. I recommend minimizing friction, lubricating, and waiting. (Also, not rubbing or examining too closely.) If it persists, you can show it to a doctor, but I don't think it's an STD.
Take care.

Speaking from experience - not expertise! it sounds like as you suggested eczema which is not contagious by the way so you wont have contacted it from your gf. I would wait for a proffesional reply but it dosnt sound anything serious that a abit of cream wont clear up.
have same problem, inflammation of the foreskin, some spots on the penis...moisteizer and hydrocortizone didnt work....maybe is fungus and need antifungal....dr rokoff?
The rash seems to have cleared up on its own?? However I have developed a rash around the bottom of my scrotum that itches like mad. Its between my scrotom and the top of my leg, looks like red bumps/spots??? Also I have a couple of blisters on my lip, I have tried everything to get rid of them but they keep re-appearing, is this linked with my rash problems?? Any ideas??

I also develop some rash on my foreskin sometimes which easily breaks when rubbed. After a few hours you wont even notice the skin has been broken. It itchs mildly sometimes. May go for a month without appearing and sometimes appear twice a week. Please help, what could this be?
