Certainly do discuss ALL of the surgical details with your surgeon, but remember that while they will do their best for you, it will be nearly 18 months to two years before it will be swelling free and maybe have changed as you go on a diet or exercise or gain weight. Maybe for a two to three day window will it be ideal. I did have to pay a bit extra because I was overweight, but my vulva was constructed proportional to my weight and other body issues. Once in place and reasonably healed, the area will reflect your weight and curvature as you are, and maybe not how you would like it to be. My gynecologist has said that I look my age and health as an average woman, no better or worse than her natal patients my age. She knows I am trans* because I told her.
