Honestly I think you just wanna have sex in general - feel up' a lady so to speak.
I also suppose that you being a virgin is involuntary celibacy and that sexual frustration of yours is cooking up some degenerate fantasies.
And just a theory here as to why this specific fantasy - your anger and desperate desire of wanting sex is contradicted by your mind in such a way that these feelings are embodied in your fantasy female, wanting to rape you.
As to what you should do - get yourself out there (well, after this goddamned pandemic) and try to find some women, be social, go to social gatherings, clubs, pubs, bars, you name it, or if you prefer being lazy and turning to decadence, as someone mentioned; a prostitue. Just try and do what you can before your frustration boils over and your fantasy starts going the other way.....
