I am THE most modest person in the world AND I like my personal space. I also had a section. Trust me when I tell you there is a LOT of touching and messing around "down there" even with a section so please don't let that be part of your decision making process. And with a section, you don't have the intensity of the birth to distract you. People are pretty much just there.
I was really afraid of birth but like someone else said, the further along I got the more I figured she had to come out somehow and I was not the first to have a baby...or even the first that day. Also, I watched someone else's home birth and it was like, OH *light blub* - it all just looked so right. And also gross, but still. It just made so much sense how we're put together to do that.
As for the modesty issue, for one thing - you have to just get it in your head that your business is nothing special to them. I have a few friends from HS who are gynos and they ended up in that field mostly because they managed to be good at putting people at ease. It's not like any of them started out wanting to see more lady business. They have seen bigger, smaller, weirder, then anything we have to offer.
Also, I had a great hospital staff. Every single person really respected that while they might have to be (oh how I hate to even talk about this) shaving me in a few minutes or checking down there, I still wanted privacy when it came to changing clothes or moving around. I guess when that's what you do, you get good at reading people. I have not one single complaint. EVERYONE was sooooo great that I did manage to just put everything aside and deal with it - it's their job. Even the after checks which looking back, I can't believe I didn't just DIE on the spot, but they were so matter-of-fact that it was so not a big deal.
I didn't believe anyone when they told me I wouldn't die of mortification but they were all right. While I am still not looking forward to my checkup next week, I am not losing sleep over it. It's their job, I have to go. No big. You just have to keep MAKING yourself not over react.
