Too many people are already confused about how they measure up to "normal." The pressure to perform up to porn star standards would drive a lot of folks to this sort of technology. No thanks. (although, maybe for the wife...

Steering this research toward treating eating disorders would seem to be a more valuable contribution to society. If they could de-stimulate the pleasure from eating in some obese people (yes, I know that not all obesity is strictly due to overeating), or use it to treat anorexia, a much healthier population could result. That doesn't make much of a sensational news story. though.
