Armpit fetish, also known as maschalagnia or axillism, is a sexual attraction or fixation on the armpits. People who have this fetish may be aroused by the sight, smell, or touch of armpits. They may enjoy licking, kissing, or smelling their partner’s armpits during sexual activities. Some people with armpit fetish may also enjoy watching others expose their armpits or wear clothing that exposes their armpits.
