Ohai, long time lurker, that's probably not going to change.
I'm currently taking a Neuropsychology course, and our reading includes the book Phantoms of the Brain by Ramachandran, excellent book about how the brain messes up.
Anyway, in the first chapter on phantom limbs, he writes about feedback he got from laypersons after he published his first findings about phantom limbs and phantom pain, particularly from amputees, and mentions two foot amputees.
Uh, I'll use the quotes directly from the book.
First, from a woman:
I'm assuming she was being modest, because he then gets feedback from a man:...I lost my left leg below the knee and I've had a phantom limb ever since... Something really strange happened to me after the amputation that didn't make sense. Every time I had sex I experienced these strange sensations in my phantom foot. I didn't dare tell anybody because it's so weird. But when I saw your diagrams, that in the brain the foot is next to the genitals, it became instantly clear to me.
Ramachandran then goes on to emphasize that patients are unlikely to make such a thing up, because it's just so bizarre to the average person....I lost my leg below the knee about two months ago but there's still something I don't understand... Every time I have sexual intercourse, I experience sensations in my phantom foot... You see, I actually experience my orgasm in my foot. And therefore it's much bigger than it used to be because it's no longer confined to my genitals.
And these people are just single amputees...
...So yeah, has the idea of Emi having phantom limbs ever been considered? (I did a search and there was only one mention of phantom limbs, but it might have happened on irc...)
If it has then I'll stfunoobgtfolurkmoar and disappear in shame.
TL;DR, Emi+phantom limbs = possibility for MASSIVE orgasms FROM HER FEET.
Just a thought.
