“Many people seeing the sensory homunculus for the first time comment on (even object to) how small the genitals are. They expect that these organs would merit an allotment of territory commensurate with their sensitivity and the disproportionate mindshare they command. The confusion comes from the multiple meanings of the word "sensitive." Sensitive can refer to high acuity. Your fingers, lips, and tongue are sensitive in this sense: generously packed with somatic receptors of every type, able to make extremely fine discriminations. Your genitals are extremely sensitive in a different sense. A penis and a clitoris can tell the difference between one finger and two, but they can't read Braille.”
