2 Nights ago had a long crazy night of sex with my GF, yesterday I noticed a couple bumps in my pubic hair region and they were rather itchy. This morning I woke up and it appears to have spread a little more (not on my penis or testicles) just in the area from the base of my shaft up to my stomach. They are itchy and feel raw to the touch. There is no pain in my urination or penis nor any signs of discharge. She mentioned today that she thinks she might have a small UTI. I have had a girls um juices on me before and got a sort of rash like this in the past, (I got checked and she and I were both std free) but not this bad. The doctor seemed to think it was either a heat rash or an alergic reation to the fluids. What is going am I allergic to vaginal fluids? Does she have an std that she just gave me?
