different name for this... what are you saying - that there was non-consensual sex in the scenario I was asked to talk about or in the OP's post?
By the way I don't think that anything I have said is an expression of the myths you mention. The premis in the myths is that a rape has happened, that there has been non-consensual penetration. The OP has said that his partner was having sex with him when he was asleep.
The difficulty is if we accept that consent is given by a series of signals that are 'reasonable' for the person acting on them to assume that it was consent, then it is not rape - it could be a whole range of things including unacceptable behaviours, but it is not rape.
Without knowing actually what went on it is impossible to accurately conclude it is rape per se with the information given. I think it is irresponsible to send the OP a message 'you have been raped, sorry :(' as a complete conclusion. Asking many more questions of the OP yes, leaping to the conclusion you have defined no.
However I go back to a point I made earlier - if you DO want to widen the definition of rape to include things that happen in sex due to misunderstandings, immaturity, consent withdrawn mentally, but not physically (i.e. no communication of the withdrawn consent), over enthusiasm etc then you will have to accept that this is a greying up of definitions.
That would explain low conviction rates, small sentences, some transmutation of charges to more minor ones, it could lead to higher reporting rates, and also to a more paranoid approach to sex across the board.
I think these are all dangers and consequences of being too willing to project onto the OP here.
Sorry if you don't agree with me.
I think the OP has probably run off because of this ideological battle rather unfairly started around the request for understanding. That's sad.
