I tried to talk my husband into one for 4yrs. Then my beautiful baby girl came alongs. We now have kids aged 13, 10 and 1 1/2. I got my tubes tied right after the baby was born. I had a bad last pregnancy and did not want anymore.
My take is this: The person who does not want kids or more kids should take the step. Sure it is less painful for the man, but someone has to get it done.
