I have a small wound on the penis with inflammation. Is this STD?

Hello doctor,

Two months ago, I used perfume and shampoo excessively after unprotected sex. I end up with inflammation on my penis, especially the top-side opening. I have to say before that I always noticed a small wound. Just mentioning it in case it is causing problems, anyway. I went to an infectious disease doctor was and given an injection for gonorrhea. Also, Doxycycline just in case, and in the middle of the Doxcycyline, he added Ciprofloxacin 750. I used both until the Doxcyline and Ciprofloxacin was over. After that, my penis inflammation was still there, it was not very bad, but it was burning sensation and stinging feeling and redness. I assumed it could be an allergic reaction so I went to a family doctor and advised me to check for STDs. He gave me Hydrocortisone and antihistamines for a week. After a week, I went to another doctor who gave me antifungal cream and tablet to use once a week for four weeks. My STD results were back negative to HIV, HCV, HBV, HSV2, RPR, chlamydia, and gonorrhea. But my HSV1 IgG was high and not IgM.

The problem was still there, I booked with a dermatologist, which I felt like the best solution. He gave me Pimecrolimus 1% and Travocort cream to use for a week, but I noticed as I was getting the relief of symptoms. My head of penis looked so inflamed, and I can send a picture. Still, recently there is more, the opening I believe called meatus when I am erect opens wider than it used to look before. The penis head's backside looks like it is getting split more exactly in the middle and going through dystrophy, which got me worried. Perhaps the medications I am using is making it worse. I forgot to say that inside of the penis, there are lines of swell, not painful, but make urinating more hard. After the first week of unprotected sex, I used something called tea tree cream mixed with some olive oil. It may have made things worse. Now I need your help, is the very tiny wound getting perhaps affected by all of this? Is it a different STD that I did not test for? Is it just balanitis, and I need a good treatment plan.
