I know to some this is a fantasy or a turn-on, but I worry about the long term ramifications of men denying themselves. There have been numerous studies that link prostate cancer to men not ejaculating enough. Most studies say 21 times a month will reduce a man's chance of getting prostate cancer by a third or even half. I get the role playing and if that's what you like more power to you, just be healthy when doing it.
Also, your wife doesn't care about this then they don't care about you and you should ditch the cold-blooded cunt.
