Re: ...to eliminate dark thoughts...

Look into Prostate massage,prostate milking, prostate massager

What exactly is my prostate?
The prostate is a walnut-sized, semen-storing gland located at the root of the penis, just below the bladder. When the prostate is massaged, stagnant semen is released and voila…your prostate is cleansed. When ignored, as is often the case, semen becomes stagnant in the prostate, creating a buildup of bacteria which can cause swelling.

So how will this benefit me?
Regularly prostate massage reduces the risk of prostatitis, prostate cancer, genital pain, symptoms of erectile dysfunction and frequent nighttime urination. In addition, it improves overall erectile function and increases seminal fluid and circulation. While the health benefits of regular prostate massage are long-lasting, you might be surprised at all the other positives in store.
