Definitely not happening here. I like the idea of having boobs that sit up again, but I am already a 10E (normally... currently a 10FF/G), so would only want a lift not implants. A lift is a way bigger operation than an enlargement as they do usually remove the nipple completely to remove the skin and make your boobs perky again. No thank-you!
Besides, in a bra they are still awfully impressive, and who sees me without a bra besides me and DH? He still likes them, so why change anything?
