The amount of physical sexual function and ability to feel pleasure or pain sensation after a spinal cord injury depends on level and completeness.In general, an incomplete spinal cord injury affects sexual function to a varying degree if at all, as opposed to complete where no function exists.
Usually high level quadriplegics cannot go without a catheter for long.
Men with incomplete spinal cord injuries may achieve reflex, but not psychogenic erections.
That is; an erection may be achieved by physical stimulus, touch, not erotic vision or thought.
Women with an IDC can also leave a catheter in during sex unless it causes problems.
Stoma and those who self-cath (pass a catheter several times a day to drain bladder) usually do so just prior to sex to avoid any unwanted urine leakage.
