I would say that arguments about GRA and self ID are limited with regards to this case.
It may have an impact on which prison he goes to, of course.
But the wider question, of how women and girls are shamed into ignoring boundaries, questioning their own instinctive responses, and overcoming uneasiness is something we also need to look at.
Crossdressing disorder is a paraphilia. A fetish.
'Transvestism is a form of fetishism (the clothing is the fetish), which is a type of paraphilia in its most extreme forms. In transvestism (cross-dressing), men prefer to wear women’s clothing, or, far less commonly, women prefer to wear men's clothing. This may be because women have a broader range of clothing considered consistent with gender. However, they do not have an inner sense of belonging to the opposite sex or wish to change their sex, as do some people with severe gender dysphoria. However, men who cross-dress may have feelings of gender dysphoria when they are under stress or experience a loss.'
