All the advises above are excellent!
It is an almost irreversible procedure, so don't consider it at your age.
You never know the future.
i tried to do this at the urology clinic at SGH when I was 32, after having 2 kids.
The doctor won't even agree to do because my kids are too young.
They had seen a lot of situations in their profession, so better trust their advice.
But i should get it done at 42.
Almost got my mistress pregnant! And other flings who might want to use pregnancy to tight me down.
