Any advice to follow to make the process easier. Before/After advice?

To give some context; I'm 31 with two children, married to my high-school sweetheart. She has gone through two traumatic births via C-section. Our original plans were for her to have a tubligation with our son's birth, but the doctor refused due to a previous miscarriage. He said he wanted to wait until after birth, in case we changed our mind. So her and I spoke about it and I agreed with her I'm fine with getting fixed. Secretly, I've always hated the idea. It scared me, I felt like I would be less of a man. However, I've watched my amazing wife get cut on three times and go through a DNC after our miscarriage. I think the least I can do is this. I just regret being such an ass in the past about it and am now looking forward to Monday.
