Hmm.. I dunno.

Not implicating anything in particular, other than that biology is ridiculously complex. I can only speak from personal experience.

Before I transitioned, I noticed there was a pattern in my life where cis lesbians were interested in me, I've even dated a lesbian cis girl _as a boy_ when I was about 15 or something like that.

Biology is very strange.

I personally use the word "soul" for this kind of stuff. But that's nonsensical in the end.

Humans rarely neatly fit into sharply defined boxes with no bleed across boundaries.

if attraction not biological how one get attracted to another? by being educated that humans generally do? there's nothing ruling out biology in that
