Not all Heathens practice "seiðr"; given its associations with both the ambiguity of sexuality and gender and the gods Odin and Loki in their unreliable trickster forms, many on the Heathen movement's right wing disapprove of it. While there are heterosexual male practitioners, "seiðr" is largely associated with women and gay men, and a 2015 survey of Heathens found that women were more likely to have engaged in it than men. One member of the Troth, Edred Thorsson, developed forms of "seiðr" which involved sex magic utilizing sado-masochistic techniques, something which generated controversy in the community. Part of the discomfort that some Heathens feel toward "seiðr" surrounds the lack of any criteria by which the community can determine whether the "seiðr"-worker has genuinely received divine communication, and the fear that it will be used by some practitioners merely to bolster their own prestige.
