What Could Penile Glans And Foreskin Swelling And Flaking Indicate?

hello how are you, I need help with a problem in the penis. a few weeks ago I noticed something strange in the penis. at first saw some red dots on the glans, now I see that almost do not look, but I notice that the glans is a little swollen and the foreskin of the penis also. Also when I masturbate I see the glans has a skin flaking and loose so it looks white and a bit dry. from what I ve read on the Internet that could be balanitis, an infection or fungus that may have been caused by sexual transmission. i read on the webpage that I use ketoconazole every 12 hours for 7-10 days, which I have in my house that I m using cream and 3 days ago. I want to know if I m doing well using the cream or if I have to use some different. I had sex without a condom with my ex to last 4 months. this happened about two months ago, they were like two or three times that she convinced me to do it without protection. and for this reason I think she conveyed me. please i need URGENT help with that, if you know about that would greatly appreciate it. thank you very much for your time
