The idea that people will casually do this is ... hilarious.
Birth control that involves body modifications is anything but casual, but to draw the line of it being ridiculous at when it involves male genitalia is a bit narrow-minded.
In my sample group, it's not as large as you think. I'm a 43 year-old post-vasectomy father and out of a group of ten close male friends/relatives I've encountered 2 close calls and 2 oops babies. And these are intelligent responsible men. The majority of the excuses range from "I just never got around to it" to "I don't want to get cut". Seriously?
That's happened to be with 2 back surgeries, one on my arm, and every filling I've ever had done.
Anyway, I'd get this procedure done in a heartbeat anyway.
