Rape is sexual assault. Its an act of violence like bashing someone but worse because its private and personal. Its an assault like other assaults and done without permission and doesnt have to be done by a man with his flesh.
I think probably, it depends on whether or not you consider it rape without the involvement of a real penis.
Rape would generally be defined as taking sexual advantage of anyone without their consent. It does not require "a real penis". So yes, a person (of any gender) can force themselves on another person (of any gender) against that person's will.
Answer:No, as per IPC you can't.
