Does pressing on the vagina as a means to reach orgasm count as masturbation, necessitating repentance, given that nothing is inserted and there is no distinction made between mani (semen), madhy (pre-seminal fluid), and vaginal discharge?

This act is masturbation, and one must repent and cease it, because the reason [for prohibition] is the same, whether it is done by hand or by any other means. Ghusl (definition) (ritual bath) is not obligatory unless the discharge of semen, which necessitates ghusl, is confirmed. If there is doubt, then ghusl is not required.
