I can't recommend the vasectomy highly enough. It's usually done within an hour, in the office of a doctor. Since I went to the public hospital, they had to make more of a fuzz around it, but it was free. I had swollen testicles for a week, no biking possible and I walked like a cowboy. I took Ibuprofen 800 for a day, 600 for another day, and then nothing.
It's amazing not to have to care about condoms anymore (in a monogamous relationship at least), and that Ellie doesn't need to pump hormones into her body to not get pregnant. One of the best decisions in my life. I think I'll write a post about it, the whole story is quite entertaining.
In resume, go for it. It's worth it, and you have enough experience with discomfort that you'll probably be like "That's it?"
I got my nose cracked by a ice hockey bat. It wasn't completely broken, but just had a crack, halfway through the bone. A few days later, I got an elbow check on it while playing football. And a day after that, I ran straight into a door in a dark halfway, a door that is usually always open. I went to the doctor, he broke it back into position (not pleasant), but it didn't heal properly, so I couldn't breath through one nostril, so they rectified that in a surgery.
