A breast obsession is an intense fascination with the female breasts. This fetish goes beyond the usual attraction to breasts that many people who are sexually attracted to women feel.
Breast obsession is the most common sexual fetish for heterosexual men in the United States, Europe, and East Asia. Some bisexual and homosexual women also have a breast obsession.
Breast obsession is also known as breast fetishism, mastofact, breast partialism, and mazophilia.
