I've got a penis implant and it works great! Ask me ANYTHING!
I was in a near fatal accident 5 years ago that left me with a spinal cord injury. Although I can walk some, I still have partial paralysis including bowel, bladder and sexual function. Thanks to modern science and an amazing surgeon, I was able to get an implant that I can inflate for a full erection.
Here are pics before my accident, post accident and pre/post surgery. WARNING: These images are of a penis and are NSFW. ALSO, the post accident pictures are graphic and NSFL.
EDIT: I'm stepping away for a bit, but still checking in and answering questions. WOW you guys have been amazing!
