Balanitis?

Hello, I hope someone could tell me what I have.
I’ve been having this red spot on my penis for two years now. One day It started to itch and the head of my penis was red and swollen, there were little red dots all over my penis head as well. I searched on the internet and saw that yogurt could help, which it did but this red spot appeared and hasn’t leave. I went to a dermatologist and prescribed me Chlotrimazole 1% and Hydrocortizone 2.5 % two times a day for two weeks (After using these, the skin looks dry and flaky now) It didn’t work. I’m starting to use yogurt again. There’s no pain or itchiness. I don’t want to go to any hospital due to the Covid-19. I just want to know if this has happened to someone before and how could I overcome this issue. I’m 26 years old, uncut. I’ve been tested, HIV, Hepapitis ABC, HSV 1/2, Syphilis All negative. Thanks
