Why is my penis hard even after ejaculation?
Patient: I'm 31 years old. A couple of months ago I started having erection without stimulation of any kind and my penis is growing and producing too much sperm. Even after the release it's still hard. i consulted a doctor and got tested. The doctor said I'm lucky and I need to release it at least four times a day. is it normal to have erection that lasts more than four hours without physical or psychological stimulation and to produce sperm 15-18ml? Doctor: hellothank you for trusting HCMDear have you feeling any pain during erection??have you feeling any hard band like structures during erection??have you suffering from any systemic diseases??erection lost more than four hours is not a normal phenomenon please consult your doctor and get scan for penile blood supply and other systemic diseases like sickle cell disease,local like peroneys disease etc..  I think I answered to your question if you have more questions feel free to ask.take care
