Well I should add. When I go, I usually get the urge to go again pretty soon after. Then I maybe wait 30-60 minutes and go with a normal amount coming out.
One question, are you infact having frequent urination or the desire for urination. If your having normal flows where your empting your bladder thats normal but if your having drips and shorter flows than normal could be a prostate infeciton.
Since the urine culture and prostate came back fine it would appear yes is not an std. Also most often with stds lke Gono and Chlanydia any infection would start off in your penis and could move up the urinary track if left untreated and symptoms would be the puss and burning while urinating. Frequent urination is often assosciated with the prostate or even a bladder infection. But since its been 2.5 month i personally feel its anxiety related.
Bottom line is that if you have a long term partner you need to have a doctor give your the ok on your condition but
Hi often frequent urination could be related to diet change from stress and over worrying. Its not an std symptom without any white puss discharge or burning while urinating.
