L-Arginine and the prostate

I've read from several sites and a few studies about the effects of l-arginine and male sexual health. As some of you probably know already, l-arginine is a supplement that's converted into nitric oxide in the body, taken from WebMD: "L-arginine is converted in the body into a chemical called nitric oxide. Nitric oxide causes blood vessels to open wider for improved blood flow. L-arginine also stimulates the release of growth hormone, insulin, and other substances in the body."

Since it improves blood flow it's been used to enhance libido, orgasm strength, erections and so on, even if all men don't necessarily achieve the same results. I was wondering if any of you have any experience with L-Arginine and Aneros usage/prostate play/anal in general? On paper you could imagine it having an effect on prostate sensitivity due to the increased blood flow to that region but what I'm looking for is anecdotal evidence.
