The MLD flap is supposed to be good, scarring isnt as obvious (can be hidden by a shirt, but is still a long incision left - but atleast it doesnt require a graft to cover the donor site.)
But just to make people aware, only a few surgeons do this type of procedure and I think so far its just the Serbian surgeons (dont quote me on that though :p ).
Regarding the urethroplasty, alot of surgeons (ok, well atleast the London team) are using the forearm flap technique now instead of using tissue from "down there" or the inside of the mouth, and this reduces the possibility of complications alot, so theyre much more successful.
Before, guys who got the pubic phallo didnt have the option of standing to pee, but now they do because of this technique, so people hoping to be able to stand to pee eventually, like you mm, atleast you know that its very possible to have it successfully done

As for the prosthesis, many guys go for it, but no, Im not. Too many complications associated with it. Plenty of guys are very happy with it, but I even have heard of one guy who has just had his 5th attempt at getting the device, fail and have to have it removed.
Obviously Id love to have the benefits of it, but given that they dont last a lifetime (apparently they last up to 7 years, but I doubt it) I would have to have countless more surgeries to replace them when they fail or malfunction, and at my young age, I really dont want to have to face more surgeries once things are finally done, I just want it to be done :p
But hey, thats just my personal take on it!
