Indeed. It's hard to believe that until relatively recently people thought that sexual attraction was fundamentally based in biology rather than identity.
The longer I've been involved with the queer community the fuzzier things get. I very much looked and acted like a guy when I was younger but was drawn to lesbians and always seemed to get along with them and they were the only people I felt comfortable talking about women's bodies with. My first 2 hookups after I started transitioning were with cis lesbians. This was before I started hormone therapy. The relationship I was in when I came out was with someone who still identifies as a cishet woman but 3 of her exes have come out as trans women in their 30s. There are so many ways to be attracted to people and strange ways we are drawn to each other. I've noticed that the kinds of people that are casually interested in me has changed with my body but my own conception of what desire is has become so nebulous.
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.
I think most cis women-who-love-women do like trans women, but they just have more options.
