Hi, I have what may be a blister on the head of my penis... i cant tell if there is fluid in it, but if there is its very little, it looks like an area that is lighter than the rest of the head. My doc said it didn't look at all like herpes and that if it was a blister it would hurt at least a bit... anyway, my question is, does anyone know if blisters or discolorations like this can be caused by something non-std related?
I have 2 months to wait for herpes tests and i need the possibility of another cause to hold on to until then as I am very stressed.
thanks
