Implants are great. If you can afford 'em, get 'em I say...I believe the latest info I read is that Plastic surgeons believe silicone "look more natural" although, as the very missed Sputnik Girl pointed out, saline is friendlier to the body.
I can't tell the difference visually or by touching. They feel great to me. They generally make the girl feel great emotionally...so, that's a major plus, in my book. I would prefer the real vs fake issue to completely leave public discussion. It is an issue which unfairly demeans women, I think.
