An armpit fetish is an intense and persistent sexual interest in or attraction to underarms. Armpit fetishists may feel attracted by the look or smell of the armpit, or both. The scientific name for an armpit fetish is maschalagnia.
People attracted to the way the armpit looks often see a similarity between the armpit and female genitalia, whether it is hairy or shaved. When someone’s armpits are hairy, an onlooker may guess they will have hairy genitals too.
People attracted to the scent of armpits are likely responding to pheromones. The armpits emit these chemical compounds which may attract others. The jury is still out on that theory, but these chemicals do increase testosterone and create individual odor prints, much like fingerprints. If you’re already attracted to someone, sniffing their pheromones may add to their allure.
Armpit fetishists may enjoy licking or sniffing the armpits of their sexual partners. They may also fantasize about licking or sniffing the arms of other people, such as people they know or celebrities. Armpit fetishists may look at photographs of people exposing their armpits or watch people, hoping for a glimpse of their armpits as they raise their arms.
Armpit fetishists may also enjoy stimulating people under their arms. They may enjoy tickling a partner until they beg for mercy or stimulating them with items such as a feather or an ice cube.
People who feel turned on by hairless armpits may be sexually aroused by the removal of armpit hair. They may enjoy watching someone shaving or waxing their armpits or even taking care of these jobs for them. As people can feel vulnerable when they’re being shaved or waxed, shaving or waxing someone else can be great fun for natural dominants.
Some armpit fetishists also enjoy armpit sex. During this sexual act, the fetishist puts their penis against the armpit, then their partner places their arm down, creating a snug pocket like a vagina. The fetishist can then thrust against the armpit for sexual pleasure, often until they climax.
