You cant be considered for a vasectomy till you are over 30 and have 1 biological child, so I been told...
So your DH should have no worries getting one....

My Dh family are shocked Ad wants one, they think I should get my tubes clamped... how ridiculous when he can be in and out in an hour!!!
Our choice is a vasectomy also... but everytime we go to talk, I just cant. I am clearly not ready yet, but I will be eventually I guess...
