Let me give you my background:
-I've had my GF for almost 6 months and we haven't had sexual intercourse, however everything leading up to that.
-I'm a virgin
-My GF has had protected sex once before.
Recently this dried up redness has been appearing on the side of the head of my penis. Furtheremore, I can barely see it until it becomes erect. When it becomes erect the side of the penis head becomes very red and the skin is sort of rippled / disrupted. In addition the skin right before the head also becomes more red than the beginning of the penis, however this only happens when the penis is erect. There has been no other symptoms.
Is it possible that I have anything? yeast infection? herpes?
Any help here would be great,
