An extreme form of anal penetration in which a fist is inserted as deeply as possible into the anus and rectum.
Like the insertion of objects such as dildos and glass bottles into the anus and rectum, fisting is a completely non-genital activity which nevertheless is considered sexual and part of a pansexualist and sexually experimentive ethic within the dominant culture of anal penetration.
For further discussion of the dominant culture of anal penetration and the Alliance's alternative, see our policy paper Multipartnered Pansexualism or Heroic Love?
