Here is a great discussion site for prostate issues. It is like 'Bike Forums' but for prostates.

One warning though...the discussion threads go from inquiries about rising PSA, to sad outcomes about guys struggling with aggressive prostate cancer, so it is not always a lighthearted place to be. But if information is what you want, from guys who have been there, it is great.
