I'm not in favor of implants. In fact I hate them. [And, in what bizarro universe are 34Cs teensy?],
But, bottomline, who the fuck cares what my opinion is?
It's your body, pretty, and hence your decision. Yours and yours alone.
Please for fuck's sake: Make sure the "knife" is talented.
Good luck with your procedure, young lady, and may you heal quickly!
