Suposedly, a thin anklet on the left ankle signifies a woman who enjoys havig sex with men other than her partner but with his full knowledge and agreement,....ie., a relatively 'open' marriage/partnership. An anklet worn on right ankle means a woman who has sex with who she likes regardless of her partner or his wishes....ie, a fully open marriage which may go as far as full cuckolding...ie., blatant sex with other men to humiliate her husband/partner.
