Here's a scenario for you. You fall in love with someone. Your lives intertwine over several years. Then, your Discussion about Where Our Relationship Is Going ends poorly. You decide to break up, but after months of reflection you miss each other for all the right reasons. You get back together. And four years later, you're married with three children, none of whom was planned.
These are friends of ours who, blessed (and a little shell-shocked) by their extraordinary fecundity, have decided they're done having children. And now the debate begins: Does she get tied, or does he get snipped? And is tying or snipping even necessary?
They've each consulted us about what we'd do in their situation, and I have to say I'm all for Option Three. There are plenty of noninvasive ways to take control of your fertility, through cycle monitoring and such; that plus condoms should work just fine. Just as there's no way I'd ask my wife to undergo a tubal ligation, there is absolutely no way I'll ever get a vasectomy. It's cliche, I know, but I like my vas deferens just the way it is.
