I had a radial arm flap for phalloplasty, and despite the fact that I have no erotic feeling in my penis, I'm glad I did it. My surgeon left my clitoris at the base of the penis, so although its not the same as "normal" sexual satisfaction, I can still achieve an orgasm.
At the time, the surgeon told me that they could reduce the size of the scar on my arm with an implant. It would be a temporary implant that they would add fluid to through a port under my skin with the goal of stretching out the skin without scarring. They would eventually remove the implant and with the skin stretched, be able to cover the scar. I just chose not to do it.
If I were going through transition now, I would have the urinary hookup and some cosmetic work on my penis, but at the time I had the surgery, the hookups were considered dangerous. Medicine and surgery have come a long way. I do wish I could stand and urinate, but am not in a position financially to do it.
For all the advancement and skill of surgeons, its just not perfect. That is something we accept when we go into transitioning. Its just a matter of weighing the imperfections against what the surgeries will do for us and how we look at ourselves.
