I'm not a lawyer but I believe that, in countries which allow this sort of explanation to jurors, it's done via an expert witness, rather than separate training, which I imagine might be seen as influencing the jury in favour of the prosecution.
Using expert witnesses to do this in E&W (not sure about Scotland) would present challenges because, unlike in the US, for example, English courts usually only have 1 expert witness on any given topic, who is supposed to be completely neutral and acting for the court, not siding with prosecution or defence. This is different from the US system in which each side has its own EWs so, if the defence thinks anything that the prosecution's EW has said is wrong or unfair, they can counter it with their own EW.
But I'm sure there must be ways to incorporate guidance to jurors to combat misleading rape stereotypes into the English system. After all, it has been done with coercive control, despite low public awareness or understanding of it, and the fine line between it and bad but non-criminal behaviour.
