Nullo (body modification)
The term nullo refers to an extreme body modification subculture made up mostly of men who have had their genitals surgically removed. Nullos are not necessarily transgender; most identify as eunuchs. They are often either asexuals or gay men. The term nullo is short for genital nullification. Though the procedure is mostly done by men, there are women who also voluntarily have their vagina stitched closed and clitoris removed.
One of the most famous nullos is Mao Sugiyama, a Japanese artist and asexual activist who in 2012 had his genitals surgically removed, cooked, and served to paying guests at a public banquet. Cannibalism is not a crime under Japanese law. Sugiyama, who uses the nickname "Ham Cybele", also had his nipples removed.
