I cannot say that masturbation has been deleterious to my prostatitis (likely, to the contrary). I was actually thrilled to read that others have the same problem that I so often experience (misery enjoys company). To me, it feels more like the sensation of someone having shoved a baseball up my behind. The pain sits there, and the area is incredibly tight and excruciating. The only thing that works for me is to jump in a very hot bath and take a clonazepam. The clonazepam is incredibly fast acting, and will cause the flare-up (which is really a form of an anxiety attack) to dissipate in about 15 minutes.
For years, I thought I had an enlarged prostate or some other prostate related condition, and was even scoped. The doctors were clueless, as they found nothing physically wrong with me. By an act of God, I went to the doctor for an unrelated illness and was unable to see my primary care physician. There was a visiting doctor from the University of Texas (a professor of medicine)who saw me. I explained to him my experiences and after looking at my chart he said, �I guarantee it�s anxiety related. I�d recommend that you take a clonazepam at the onset of any attack, and that will likely remedy the matter�. He was right!
Another suggestion� if you have a significant other who is willing, have her consider learning about prostate massage. It is not something you want to do daily, or even weekly, but I have learned that it is a wonderful form of preventative medicine.
