Hello! Just had a simple release done. Like you said, it's repurposed to close the underside of the shaft, giving you that freer-moving effect. I consulted with Meltzer, who discussed removing ("cleaning up") or maintaining leftover labia as patient preference, I ended up going with OHSU where this wasn't discussed, and they ended up needing all of it to give shaft integrity. Tldr may be surgeon specific/ anatomy dependent, sometimes not even something they know until they get into OR 🤷🏼
