I certainly don't intend to tell you how to live your life. I also don't know what reasons you may have for wanting the surgery. However, if your reasons are cosmetic, I'd simply offer one guy's opinion: your natural figure is just as beautiful as anything the doctor will be able to do for you. Sure, you may come out "perkier" but that may come with scarring and loss of sensation. Plus, you can rest assured that many men understand and appreciate that well endowed women do not defy gravity.
Best of luck in your decision.
