Coping With Prostatitis

I was having this problem and I still have it, 5 years ago I noticed yellow jelly bubbles in my siemen [semen] when I ejaculate… I was so afraid that I didnt visit any doctor then… and I lived with this “problem” just fine without any obvious problems in my health.
This year I decided to visit a doctor (urologist) I made some siemen [semen] and uria [urine] analysis and they didnt find any infections but my siemen [semen] count was 13 million per ml. The doctor decided to give me ofloxin 400mg for 40 days, the ofloxin didnt help enough, the yellow jelly bubbles reduced for few days but they came back again, I repeated again for another 30 days the same antibiotic… with the same results. Because my main concern are the yellow jelly bubbles that I have on ejaculation, I read a lot of articles that can help to treat this sickness.

1st: When I drink plenty of water every day (approximately: 1 big glass per hour) the yellow bubbles in sieme [semen] are reduced or almost vanish from siemen [semen] in ejaculation.

2nd: I consume the following every day: Quercetin, Zinc, Selenium, Saw Plametto, Cranberry Capsules (better with a lot of water), (L-Arginine L-Ornithine L-Glycine in 1), Copper, MultiVitamins like C,E,B-6,B-12,B-CAROTINE, and MultiMinerals without the above ones.

After 3 months I made another siemen [semen] analysis and my sieme count got better approx 18million per ml.

I believe I can live with this yellow bubbles if my siemen [semen] is okay, I never had any pain in ejaculation or in the prostate, but I want to know what I have, I assume that it may be prostatitis, because I check my testicles for anything else and I dont have anything wrong. But the big question is what kind of prostatitis do I have? If is bacterial or non bacterial and why when I drink plenty of water the yellow bubbles in siemen [semen] dissapear? my siemen [semen] got better because of zinc, selinium and other supplements?
