Somewhat OT, but I am a quadriplegic due to a spinal cord injury when I was 14. My cord was completely severed (which is rare) at the C4 vertebra, so I have no movement or sensation from my collarbones down. And I’ve had plenty of orgasms. I never had one as an able-bodied person, so I can’t say if it’s the same sensation as you folks have. But it is still quite pleasant. And though I can’t feel my nipples, they become erect during stimulation and orgasm. The point of this little rabbit trail? The human body is remarkably resourceful when it comes to sexual function post-illness, -surgery, or -injury. I think you’re going to be just fine.
