The act of removing all visible indicators of gender and sexuality, including body hair, breasts, genitalia, etc.
Often part of master-slave domination-based S&M relationships, these removals are generally performed in an unsupervised and unregulated environment through amateur surgery, making them incredibly risky.
Master - "Today we are going to begin your morfe process by placing these rubber bands around your testicles. As the blood flow cuts off they will eventually wither and die, and may be removed."
Slave - "Mmmmfff mm mmmm mmfff hmmmm!"
