When I got sterilized, the doctor asked me if I was in a committed relationship. Told him I was. Then he said that I need to treat this as permanent. Told him it wasn't a problem. He pushed a little more but inevitable told him that if things changed and I ended up with a woman who wanted children, adoption was an option. That ended it for me, and I was able to get the procedure done. I don't know if this is typical for men, but that was my experience.
