non-consensual (adj.)
also nonconsensual, by 1945 in legalese, from non- + consensual (q.v.). Used since 1960s by sociologists and in political science; used by 1977 in legal discussions and definitions of rape and other sex crimes and popularized in this sense from c. 1995. An earlier adjective was non-consenting (1670s), which was used of persons, not acts.
