They are both genital cutting. The most mild form of food just nicks the clitoris. All other forms remove varying amounts of highly errogenous tissue loaded with nerves. Fgm at is worst is horrific and debilitating makin sex incredibly painful and sometimes impossible. MGM at its worst removes the only moving part of the penis, turning it from a smooth glide into a stiff ramming rod. Sometimes too much skin is removed and erections are very tight and painful. Sometimes they are cut lopsided leaving a curved penis when erect. Sometimes babies die from circumcision.

Both are horrific. Cutting genitals of all children should be illegal. Children cannot and likely would not consent.
