Thanks for your replies, ladies, I really appreciate it!! I might talk to my GP and ask what the waiting list for public is like, I probably won't be able to get it done until after Christmas anyway because of the cost so if I can save money and have a similar waiting time then I'm happy to do so.
Kate, I personally would LOVE for DH to go get a vasectomy but for some reason he is just 100% opposed to the idea and would rather be the next Family Duggar than have anybody go near his bits with a scalpel Such a big baby!! And he's even less keen for more kids than I am, he just *really* doesn't want to 'lose his manhood'
