There's a secret about vasectomies that you don't discover until you're committed to the little operation. You have to have a lot of sex before it works. The actual operation is quite simple and painless: a bit of intravenous Valium takes your mind not only off your balls being cut on but pretty much everything else as well, and you're out of the doctor's office inside of 45 minutes. There's not a whole lot of pain afterward despite the location of said surgery, and you're back on your feet in a day or two. You can resume sex anytime you feel up to it; certainly within a week in most cases.
