Nipple sensitivity was very important for me as well. Something I enjoy during sex with my wife. So I too had the same conversation with my surgeon. He said that the procedure he wanted to do is not a 100% gynecomastia although that's what I called it. It's a combination of Gynecomastia, Lipo and breast reconstruction done with a certain surgical technique. I think it was actually called a Bilateral Axillery Skinfold excision, Superior pedicle nipple graft combined with Lipo suction. He said it was a complicated procedure and that there was a chance I could loose the sensitivity if the nipple lost blood flow for a significant amount of time during the procedure.
I can tell you that my nipples are very sensitive at this point. Now that i'm off the percoset. I feel the nipples rubbing against the compression shirt when I move/adjust the shirt at times. The shirt has a tendecy to ride up. Which I then i have to pull taught. Which i believe is a very good sign. He said that he had to leave some breast tissue in as that's what also keeps the sensitivity going.
I have pictures in my profile. I showed you mine...now you need to show me yours.
