This is an old video I saw many years ago, ok it's not an aneros he uses, but the idea is the same. If I were to attempt this I would use an aneros device.
This guy has a constant erection, probably a super e by the looks. He watches porn and is constantly aroused. A big problem for me is that I loose arousal in session very quickly, the river of pleasure I feel fades. But I am able to reactivate the prostate if I somehow get myself aroused enough again.
So, does this work for anyone else? Or does it confuse the brain? Does anyone want to try this out as well?
