Culturetest no bacteria have all symptom

I have had a masturbation habit for the past few years. About a year ago, I developed a urinary bacterial infection and underwent a culture test. The doctor prescribed a 5-day course of antibiotics, but due to my masturbation habit, I would masturbate during the middle of the course, resulting in the infection not being cured. I have taken multiple courses of antibiotics since then, with the last one being Zocef 500 for 5 days. However, I masturbated before completing the course. Now, my problem is that I still have all the symptoms I had initially, such as yellow urine and a burning sensation while urinating. However, the culture report shows negative results, indicating no bacteria. Can someone please help me understand what to do? It has been 6 months since I stopped taking any medicine, yet I still experience all the symptoms. My general physician not prescribing any medicine Because culture report shows negative no bacteria But I have all symptoms yellow urine and burning while
