troilism: a
paraphilia of the mercantile/venal type in which sexuoerotic arousal and facilitation or attainment of orgasm are responsive to, and dependent upon observing one's partner on hire or
loan to a third person while engaging in
sexual activities, including
intercourse, with that person [from French,
trois, three]. A
threesome or group-sex party does not, per se, constitute a paraphilia. There is no technical term for the reciprocal paraphilic condition of being observed by a third party while on hire or loan. (
adjective,
troilistic): the condition in which a person is dependent on being the third member of a sexual partnership, or on fantasizing being so, in order to obtain erotic arousal and facilitate or achieve orgasm. Typically, a husband arranges that his wife has another male partner, so that he can fantasy her in the role of a
whore, without which he cannot become aroused.
