Painful urination only when sitting, and only when done with a bowel movement, no pain when standing. my bowel movement is 1every 2days. what could it be please?

With this scenario I would be thinking of prostate congestion or prostate inflammation/infection. A physician or urologist could determine the status of your prostate by performing a rectal examination and then advise you about further testing,including urinalysi s with microscopic examination of urinary sediment and a urine culture&colony count. Then treatment options will be discussed.
