Hi doctor, hope you can help me with this. Yesterday morning (about 28 hours ago), I woke up with a morning erection, then decided to masturbate, even though my bladder must have been quite full, or at least half full. I usually masturbate after I have been to the toilet. The masturbation was quite short lasting, lying on my back, quite gentle masturbation, not rough, but at the ejaculation point, it didn t feel very good, a little painful during, which I haven t experienced before. I think it must have been related to the bladder not being emptied first. A few minutes later, I possibly made a second mistake, by urinating. It did seem like the urethrea was not ready for urine yet, took a while to succeed. Is it advised to wait a while before one urinates? Then during the day and night I have felt rather uncomfortable, mostly during the night, some pain/discomfort, which feels like it is located at the point where I usually feel if I need to urinate or not. Is this bladder pain? It helps a bit to urinate though. Could I have had some urine in the urethrea accidentally mixed together with the sperm during ejaculation? And is this harmful? I also wanna mention that the night before this I ate two oranges and quite much chocolate, which could make the urine more acid and harmful? I have not had sex for a long time, and never unprotected, so STD is out of the question. Now I am taking some ibuprofen and also some cranberry capsules. Not sure if I should see a doctor yet, since this is so fresh. I have a tendency to see doctor too often and worry about health matters. Could you please shed light to what might have happened? Does it sound like a temporary problem? Or will I next time also feel discomfort during ejaculation? I haven t tried masturbating again, since I think I should rest the system for some days.
