For some ones who has big penis that the skin form penile shaft is too wide or ones who regularly strap the tip of penis to the buttock crease to hide the penile shaft during dressing as a woman that will make the penile skin wider and longer, if we use all parts of the penile skin to make the labia minors, the labias will be to wide and too thick which not be a good esthetic appearance of the labias.
The 16th edition is a reversion of the 15th edition. For this technic, we separate the penile skin into 2 parts, one to make the labia minors and the outer part to make the inner side of labia majors. We need the proper design on the penile skin to make the proper size of the labia minors, while the rest of penile skin can help in reducing the tension of the labia majors ,so we can get more scrotal skin graft to make the deeper neovagina. The labia majors are usually made by scrotal skin ,but in the type half of them from the penis and the other half from the scrotum.
