Drugs that affect the spinal cord

Losing your lower legs is terrible. But isn't as bad as spinal cord paralysis/paraplegia.

I dont care what others say or think about the story, L liked it all. I am disabled and spinal cord damage, so any story I read and get an erection reading, ha its a hot one for me, thanks for the mornin wood.

Unlike nerves of the spinal cord, the peripheral nerves that connect our limbs and organs to the central nervous system have an astonishing ability to regenerate themselves after injury so yes the optic nerve can regenerate because eyes are an organ of the visual system and the brain is an organ of the nervous system.

even for the subject, but I enjoyed it. I didn't get off -- I have a spinal cord injury that cuts off _everything_ [control and sensation] below my mid-chest. But I still enjoy reading about sex, even if I can't do anything about it. I've read most of your stories, and enjoy them more than most authors'.

Thanks for the comment. All spinal injuries are not created equally. The injured person described is fictional, although based upon some real life experiences. One, a cousin of mine who never lost his sense of humor, was as you described - able to use a motorized wheel chair and even drove with the addition of hand controls (paraplegic), however the other was as I described - bedridden.
Quoting from Wikipedia:
quadriplegia, is paralysis caused by illness or injury that results in the partial or total loss of use of all four limbs and torso; paraplegia is similar but does not affect the arms. The loss is usually sensory and motor, which means that both sensation and control are lost. Severity depends on both the level at which the spinal cord is injured and the extent of the injury.
An individual with an injury at C1 (the highest cervical vertebra, at the base of the skull), will probably lose function from the neck down and be ventilator-dependent. An individual with a C7 injury may lose function from the chest down but still retain use of the arms and much of the hands.

And you are correct; some quadriplegics may be able to have sex, but some are not: Although spinal cord injury (SCI) often causes sexual dysfunction, many people with SCI are able to have satisfying sex lives. People with SCI employ a variety of adaptations to help carry on their sex lives healthily, by focusing on different areas of the body and types of sexual acts. Neural plasticity may account for increases in sensitivity in parts of the body that have not lost sensation, so people often find newly sensitive erotic areas of the skin in erogenous zones or near borders between areas of preserved and lost sensation. Drugs, devices, surgery, and other interventions exist to help men achieve erection and ejaculation. Although male fertility is reduced, many men with SCI can still father children, particularly with medical interventions.

Second paragraph, 'struck a cord', it should be spelled chord, not cord. The phrase uses the musical term chord, not the one that means string.
