@LittleWingSoul I had the awful pain (nipples on fire, anyone?) with my first, it turned out she wasn't sucking correctly!
I also had pain (which wasn't quite as bad as the first time round) which I think was just normal for some people. It wasn't caused by anything and after using nipple cream it went away!
If I wasn't so pig headed I would have given up BF my first due to the horrific pain, and I would never have considered BF my second.
I also agree with you RE covering up. With my first I wore something called a "Bebe au lait" which drew attention to the fact I was feeding.
I see some BF mum's who pull their top down and a lot of their breast is exposed (although you can't see the nipple, so really you're not seeing more than you would see compared to someone wearing a low cut top) but I find it easier pulling my top up (sometimes I wear a vest top underneath to pull down just to keep my tummy covered, other times I don't need to because my top is baggy) and to be honest, you can't see any flesh unless you are right next to me. Most people walking past me probably wouldn't even know I was feeding!
