The name given to sexual acts performed to/with horses (or other equines, including Zebras). Often performed by females, for the
pleasure of a surprisingly broad audience of males. Most beastiality acts refer to equestrophilia, as the phallus of a horse is adequately long so as to provide good visual appeal (apparently).
Two of the most renowned equestrophile 'actors' are Kitty Beatty (who actually worked as a vet, before agreeing to do equestrophilic films) and
Michael Abbott (who is quoted of having no experience with horses until he purchased one for his
wife - who revelled in the thought of equestrophilia, which drove him into his new career of delivering anal sex to horses).
