Hi there, so about 8 to 9 months ago I all of a sudden noticed a sort of somewhat darkish red patch on the side of the head of my penis that randomly appeared. Along with it about the same time I had rather bad dry skin as well. Now this all started during the winter time, and I normally have issues with dry skin, but not normally down on the ehad of my penis. Another thing to mention a few months prior to this ever happening, I had sex for the first time with a girl, and it was unprotected, and sometimes it was protected. I was mainly getting lots and lots of blowjobs from her. One time she was even on her period and got blood on my penis. Washed my penis every time after any kind of sexual contact with her, but not so thorough it would damage the skin or whatever. Another thing to mention, about a week after that, I had gotten a ******* from a different girl, and by the end of the night, she had been smoking cigarettes for a long while, and gave me the *******. (Gross I know, was drunk lol) And one more thing to mention is that these past couple months, I all of a sudden am getting these random "flare ups" on the ehad of my penis where the redness is. It will come and go randomly. It doesn't exactly itch, but if I rub the skin, I get a sort of relief feeling, but at the same time it is making it worse. I have gotten std checked a couple times the past few months and came back negative for whatever they had checked for. But with all this said, is what I described could be some sort of fungus infection? Or hpv or an std of some sort? Appreciate the help much, thank you! I don't know how to add a photo of what the head of my penis looks like, otherwise I would take a picture btw.
