I agree, Rhu.
I have personally known, very well, I might add, four men who had a vasectomy w/o ever fathering any children b/c they absolutely, positively NEVER wanted them. EVER.
I mean, can't they be trusted to know what is best for them and their own lives?
Is it so bad, that they never want them and are sure that they won't change their minds?
How pitiful to disrespect them so much as to assume they are incapable of making a decision like this about their own bodies and their own lives!
Do you feel that way about your own children?
The same women who decry men taking such measures would probably scream blue murder if someone assumed women couldn't make informed decisions like this about their reproductive lives.
FWIW, NONE of these men has a single regret.
I was married to one of these men for 7 years.
He used condoms during non-monogamous relationships, but he never to make sure he protected his decision about his life as much as possible, so he took steps w/his own body to see that through.
