2) It's not crossed wires, idiot.
3) The scenario you are clumsily trying to refer to - idiot - is a hypothesis proposed by Vilayanur Ramachandran, which, by his own account, was sheer speculation based on the assumed layout of sensory areas on the cortex, where the genitals are next to the feet.
The underlying logic is vague, however, since this would sooner suggest stimulation of the feet would be experienced as sexual; there is no reason why this would make other people's feet seem sexually arousing.
It is very tenuous and you should not spout it as if it is rock-solid fact unless you enjoy being called an idiot by strangers online.
