How is it debunked though if people legitimately experience it? And isn't it possible that someone can be both trans AND have this, but also they often don't overlap (meaning a trans person could not have this whatsoever, or a cis person could 100% have this and still be cis?). I mean, I just don't see how we can discredit that something psychological exists (and as ubiquitous as having a fetish, which could literally be anything).

Just because it could have overlap with the experience of being transgender doesn't mean it isn't a distinct thing. I personally have what one could dysphoria about my reproductive organs and honestly want to not have a uterus or breasts, I just have a disdain for traditional gender roles and the idea that I must have babies when I don't want them and body dysmorphia, which have existed within me since I was a preteen, I still very much identify with feminine clothing and femininity and have no interest in being a man.

I guess I don't see why we're discrediting OP's own lived experience.
