I have had quite a bit of training in using biofeedback for self-relaxation & pain relief. It was part of learning to deal with chronic pain. (I also learned self-hypnosis.) I got good enough at the self-relaxation that I was able to stop grinding my teeth which really impressed the instructors. Hearing about the sex aspect, I am going to have to look into this more & feel slightly miffed not to have been told about this! Then again, why would they tell a 17 yr old? It would have been a little pervy, now that I think about it,

The nerd company would sound like a lot of fun! We already have a thread full of nerds from which to recruit! less

I think the sexual aspect of biofeedback is quite underrated. I know of only one sexual device, I think it's a kegel egg by Jopen which will vibrate if the vagina is squeezed correctly. And the kegel devices which give any form of feedback if the exercises are done correctly.

On the other hand there are a few bio- and neurofeedback games available like games you run a starship with your relaxation level or raise a flying device with your level of concentration.

I would love to invent more toys that combine the sexual and the biofeedback aspect, like a vibrating egg that will only vibrate if you are incredibly relaxed. After an adaptation period this should lead to mind-blowing, almost trippy orgasms. less

That IS quite a sacrifice! WW, I'm awed and humbled by your philanthropy and humanitarianism, your selfless desire to give and give of yourself.

I shall commence the plotting of new torture devices--er, ahem, sexual stimulation devices--forthwith. less
