For context, I got mine done just over two years ago. No complications (as of yet…). I’ve also got two kids already.
A few guys at work were absolutely baffled by my decision, and I even heard one was questioning my masculinity.
I got the snip when I was 28. Specifically sought out a scalpeless procedure.
Worst part was the awkwardness of just being on the table naked with some dude going to work on my genitals. Virtually no pain, really for me. The only time was when I decided I was done being particularly lazy/careful and did some cooking. Needed to crouch to get a pain and was VERY uncomfortable.
If you know you don’t want (any, or more) kids, just don’t. Generally speaking, the side effects are worse for your partners to use birth control etc, and its just a one time thing for you.
