I had sex a few days ago without protection and without a great deal of lubrication. I felt, during sex, that I may have irritated my penis skin without the use of ample lubrication. The next day and the subsequent two days I've had red, itchy patches on the glans and the inner foreskin that are also flaky. I'm thinking that it could either be a yeast infection or friction irritation. My partner has something similar, but not as itchy and more sore as a result of not using lubrication. I ruled out herpes, as there are red patches, not sores, on my penis.
