I had Brachi inplant in 2009. I found out that I although I have the same sensation of having an orgasm and ejaculating, no sperm came out. I went to see the specialist that did the operationand he said that it was noirmal. I now have a painfull erection with a huge bulk all the way from the base of my penis to almost up to the head. The head of my penis curve up almost 90 degrees and I can feel the blockage of sperm in the passageway from the prostate. What can  be done to release all the old sperm collected in the passageway
