we have only 1 child and we are seriously talking about vasectomy. He is 100% sure that he doesn't want any more kids no matter whether he gets a new partner one day. However, if i were to get a new partner who wanted kids I would probably have more, so a vasectomy is the obvious choice for us.

I agree with the ohters, it is no one elses business what you do with your own fertility, only you and DH know whats best foryour selves.
