>The word ‘toy’, and all that this implies, however, may be inaccurate or anachronistic in historical contexts. Use may not have been exclusively sexual or for the pleasure of the user. Such implements may have been used in acts that perpetuated power imbalances, such as between an enslaved person and his or her owner, as attested in the recurrence of sexual violence in Roman literature (Kamen & Marshall Reference Kamen and Marshall2021).

Feels like some interesting/important context. Thanks for link OP
