Breast implants are not good to have. Why would you want to cut up your breasts? For one thing, they look fake and make you look cheap. For another thing, it's putting a foreign substance inside your body which makes you vulnerable to all kinds of nasty complications, many of which can be seen from the outside and are not pretty. And finally, implants are not permanent and if you get them, you are pretty much bound to keep having surgeries to maintain them ($$$).
I've always had small breasts (34AA-A), but I've learned to love the small ones. My husband does too; in fact, all the men I've ever been serious with have actually preferred smaller breasts to large ones. I'm currently using the Brava system to round them out again after breastfeeding and gain just a little volume, like up to a B cup. But I have never seriously considered implants. They look obvious, and can really damage your body. They even seem to be going out of fashion. Bottom line: natural is always better!
