I have been toying with this idea for my sub and was wondering if anyone might have some experience with this concept or some ideas of how to proceed. My poor sissy is continually locked in a CB-6000 and while obviously he can not achieve a full erection or pleasure himself, he still can become erect in the CB. It may be a bit uncomfortable but not totally unbearable. I was wondering if there would be a way to train the poor sissy not to become erect, so that on a routine basis he would always remain soft. After all there are many so called "normal" men who become impotent or loose their erection. Was wondering if some sort of bio-feedback mechanism is available, etc. I can not think of anything that would be more emasculating than that! I do not mind using a device to train him to stay soft but would eventually like this condition to remain without a device. Makes my heart tingle to think of parading around in front of him and his not being able to get it up. All thoughts or suggestions welcomed!
