Even though you are 99.9% sure, I don't think it hurts much to wait. Birth control isn't all that inconvenient.
So ... what are you saying ... that a woman who is 99.9% sure that she doesn't want kids and wants her tubes tied is still incapable of making that rational decision? And that a male doctor knows better??

I have no doubt whatsoever that many people that have their tubes tied change their minds and regret it later. Well, guess what ... regret is part of life. It teaches you to make better decisions.

Women who quietly buy into the "Father Knows Best" attitude of paternalistic organizations in this country are feeding the unspoken belief that women are too silly and stupid to know their own minds and too unpredictable to be able to control their own bodies and make their own decisions. NO ONE knows what I want better than I do. And if I'm wrong later on down the road, well, so be it. I'll deal with. My mind, my body, my choices ... I don't need Ward Cleaver patting my hand and telling me "There, there, dear." Puhleeeesse.

My boyfriend got a vasectomy years ago. No one questioned him, or told him he would regret it, and the doctor sure as heck didn't refuse to do it! If any doctor ever did the condescending, patronizing crap to a man that they do to women everyday, there would be a lawsuit, and quick, I promise you.
