Also known as meta, this surgery is used to create a penis. Many surgeons will require that the patient be on testosterone for a certain number of years prior, due to the nature of the procedure. That is, metoidioplasty uses preexisting genital tissue to construct said penis; and one of the side effects of testosterone is that it results in an enlarged clitoris, which would give the surgeon more to work with.

If one were to add 'urethral lengthening' to their metoidioplasty surgical request, then they would be able to pee standing up (once healed from surgery). Otherwise, their new phallus would not be involved in their personal pissing process.

Whether or not one would be able to engage in penetrative sex will vary from person to person. It depends on various factors, such as how much material there is down there for the surgeon to work with. As it is possible to get phalloplasty(which often results in a larger size) after meta, some individuals will do just that.
