It's quite clear by now that it has practically nothing to do with gender incongruence, i.e. trans folks, doesn't mean that it doesn't exist as a paraphilia. That is, just because Blanchard got his theory wrong based on incomplete data and probably a good dose of being born into certain social constructs doesn't mean that no cis men get aroused at the thought of them as a woman. It is, as the study in the comment you replied to shows, actually quite common.

Gotta distinguish between the phenomenon auto[gyno/andro]philia (exists), Blanchard's interpretation wrt. trans folks, (falsified), and TERFs (hateful anti-science assclowns). Otherwise we'd be kink shaming.
