Gabriel Mack is a female to male trans who describes himself as an asexual gay man with a penis and a vagina. After a double mastectomy and a phalloplasty surgery creating a penis out of a chunk of skin carved out of his thigh, Mack explains what all is involved in the process. If you just google his name, you'll see the cover of New York Magazine with his picture there showing his gruesome huge chunk of skin missing from his leg that he had made into a penis. Here he is.
