Not a doctor but we did learn in nursing school that your dick is operated by your spinal cord and not ur brain, so while the brain can influence the process, the spine is in charge and doesn’t need the brain at all! Obviously this isn’t super specific and an anatomy expert can go into your detail. Feel free to correct me school was long time ago and that isn’t used in my specialty,

Your spinal cord is a superhighway for your nerves if you can feel a wedgy your spine is working so being locked in doesn’t affect your spine that much
