Sure, no problem. Essentially what phalloplasty does is take a flap of tissue from a donor site on your body and use it to create a phallus. Every flap includes the skin, some tissue from underneath it, blood vessels, arteries, and nerves. While there are a wide variety of donor sites to choose from (most of which I can't tell you about because they've become so uncommon), the most common ones you will see used today are RFF, ALT, and MLD.
RFF - Radial forearm flap taken from the forearm
ALT - Anterolateral thigh taken from the upper part of the thigh
MLD - Musculocutaneous latissimus dorsi taken from the upper side/back
Each of these has their own pros and cons, and in my experience, it is incredibly beneficial to meet with a surgeon as early in the process as possible to get an understanding of which sites are an option for your body type or what you would have to do in order to use the donor site you want (mostly related to weight loss, body fat percentage, or permanent hair removal). There are major differences to each one that would require a huge wall of text.
Phallo.net is a good resource to do some initial learning on. Microsurgery is the re-connection of the nerves from the donor site to nerves in your groin area to establish erogenous sensation. Of the three above, the only one not likely to have erogenous sensation is MLD, as it uses a different kind of nerve.
Most surgeons typically couple phalloplasty with other procedures such as a vaginectomy, urethral lengthening, scrotoplasty, glansplasty, and the implantation of testicular and erectile devices.
It is a lot of information. I spent about 6 months reading up on everything, and I still learn new things.
