brain spinal column pelvic nerves information transfer

• We get erect or wet as the result of an impressive chain of events:
  • brain perceives a sexual message
  • brain sends a message down the spinal column toward the pelvic nerves
  • pelvic nerves send a message to the small blood vessels radiating out from the pelvis
  • blood vessels receive the message and get to work: they dilate, allowing more blood to flow in
  • increased blood flow fills the penis or clitoris, making it hard, and triggers the wetness that eventually sweats through the vaginal wall into the vagina
• “Sexual dysfunction” is when the brain–spinal column– pelvic nerves–vascular system information transfer doesn’t work smoothly ... the information transfer between brain and spinal column, between spinal column and pelvic nerves, or between pelvic nerves and blood vessels; the nonresponsiveness of the blood vessels once they do get the message; or the dis- ruptions created by diseases like diabetes, high blood pressure, arteriosclerosis, and Alzheimer’s
• the spinal column also carries our emotions, which are basically simple electrical impulses ... the message “Alert—sexual excitement, prepare for pelvic hydraulics!” is carried down the same pipe as the message “I don’t trust you, mister,” or, “What the hell am I doing here?” These emotions serve as noise, which can prevent a clean sexual signal from getting all the way to the pelvis from the brain ... not enough signal to create vasocongestion down there, or to keep it flowing after it starts
