Many surgeons will create a small protrusion for a nipple in the nipple/areola graft, but not all surgeons do this. Also, this protrusion can flatten out on some guys.
Sensation will likely be under the graft, not in it, as the nerves in the nipple stalk are cut and are not microsurgically connected.
ps. Here's a recent set of surgery photos from a patient of Dr. Agarwal. It looks like she created nipples in the graft. Maybe she has updated her procedure since your consultation.
