I am a 25 y/o male who has diabetes. I have noticed for the past nearly two years that I am unable to ejaculate like I used to be able to beforehand. The feeling of orgasm is there, but no semen ever ejaculates. Occasionally it will, although weakly, but most of the time the seminal fluid is all that comes. Then, almost every time after an orgasm, I will feel the urge to urinate and notice what appears to be sperm in my urine. What could this be?
