I am facing discomfort after ejaculation or errection in penis. Elaboration- I feel pain/ stress/ a kind of force acting inward in lower part i. E in nearby inside anus. This problem starts after few hours from ejaculation and lasts up to 2-3 days. After that I feel absolutely normal. Due to this problem there is a pain during urination and takes alot of time. Recently I a performed a testings like ultrasound, urine test, blood test and semen culture test. Etc but the reports are normal. In semen culture report a virus named" stalophylus aureus" has found. For this my doctor has prescribed me a lot a antibiotics but I didn't get a +ve result. Please help sir! I am just sick and tired because of this.
