It's genital mutilation. If you get through it without pain, which is the majority of men, then it's fine. The number of men that have issues is downplayed "for the greater good". When it happens to you (bad outcome) you end up in a world where no one, NO ONE, can really tell you exactly what you need to do to fix it.
We are trying to decide here how to move forward to call attention to this problem. Men need to know that there is a significant statistical chance of lifelong chronic pain and in your case disfigurement.
We are here for you. If your pain is not bad count your blessings. You can get some help and learn to forget about it. I'm confident you can. I'm at work right now uncomfortable as usual but moving forward. Yes, vasectomy can fuck your life up pretty bad.
