Is a woman's passing of a device over her vagina considered masturbation, and what is the ruling on her using this device due to pressures and seeing handsome men at work while her husband lives in another country?

One must avoid all means that arouse desires to prevent falling into the forbidden act of masturbation, which occurs by the expulsion of semen, whether by hand or any rubbing tool. It is also necessary for women to avoid mixing with men to prevent falling into forbidden acts, and communication with the husband is required for his presence to avoid falling into immorality.
