@Gingeh I was wondering the same thing about myself, but in a slightly different way :blobfoxlaugh:
My preferences shifted massively since I've been on E.
Considered myself to be bi before my transition, but with a decently strong preference for women, now it's flipped.
I heard someone say previously that, at least for them, they probably always had an interest in men (for their example), but couldn't see themselves as being in a relationship with a man, as a man. But being in a relationship with a man, as a woman, felt right.
I'm wondering if it's close to that? That once the dysphoria starts to be alleviated by HRT, a lot of other things start to 'click' or fall into place? Or if E maybe does have some sort of an effect :blobfoxthinking:
