Results despite pre-existing nerve damage?

I had a spinal cord injury a while back and i have sensation, but not 100%, i have some muscle control, but not 100% (i can use a walker to stand up as exercise but i use a wheelchair) and i can get erections, ejaculate, and orgasm, but its very challenging and i can only do it maybe 1x or 2x a month and only with a specific tenga egg and porn.

I have been experimenting some with a helix syn V and i also have a njoy wand, which helps because i can’t exactly control my pc muscles. I know that the connection between my autonomic nervous system and my brain is impaired, is anyone in this community aware of information related to this issue?

Or if not, do experienced users have suggestions for experiments that could help me? Different toys or techniques that don’t require really fine motor control of pc muscles or something that gives a little more simulation?
