Haven't had a boob job, but had a lump removed, and the surgeon planned to go through the edge of the nipple to reduce scarring. The lump was in the right edge of my right breast, so I suggested that he take a direct route under my arm instead. I wasn't worried about a scar. Well, I'm sharing this because the surgery was done in March of this year, and the scar is still red and tender. I think this area is more sensitive than even the edge of the nipple. If they will do your surgery through the belly button or the nipple, I'd suggest you go that route. I've had two lapriscopes through the belly button, and they healed very quickly.
By the way, I'm naturally a good B cup and don't plan an enhancement, but if you and your husband want it, I'd go for it. Not sure about a D or DD though. My mother was a D, and they were very heavy. She had grooves in her shoulders from the straps. My grandmother was 4'11" and a DDD. She suffered due to their size. She died before breast reduction was possible, but she wanted to have some of hers removed. Somehow, the gene skipped me, and actually I'm glad. My husband says more than a handful is a waste
. Both my daughters are C's which is about right.
