How to manage recurrent fungal infections on the penis?

Hello doctor,

I had a full body to body contact with someone at a massage parlor three months ago. There was no intercourse or oral sex. I ejaculated. I got diagnosed with scabies and a fungal infection on the penis. I took medications for the same and the symptoms went away. However, the burning during urination did not stop. I took other tests and got diagnosed with bacterial vaginosis (BV). I took antibiotics for the same. The fungal infection again came back last month at the tip of the penis even though I had no sexual contact. I took an antifungal again and applied Onabet. The infection cleared up. Today, the fungal infection again came back even though there was no sexual contact. Do I need to take any tests? I have attached the pictures. I have taken all thenine Polymerase chain reaction (PCR) testsafter nine weeks of contact and enzyme-linked immunosorbent assay (ELISA) and venereal disease research laboratory (VDRL) after six weeks of contact. All came negative. I have been having pain in the nerves of my lower back since the contact. It goes away and comes back in a week or so. It is recurring and makes difficult to change postures while sleeping and sitting for long intervals. Sometimes, the pain is very severe. It makes me very difficult to stand or sit. I checked C-reactive protein and it was normal. Both semen culture and semen analysis were normal. But, there is a problem with a backache and itching and infection in the groin. Please help.
