I'm a MTF transsexual. I'm attracted to those who identify and live as a woman, biologicly and non-biologicly. I have a difficult time searching for a term used for this sexuality. I came across the term femmesexual, but am not sure it's quite the correct one for this specific detailed explanation I just gave. I don't think "feminine" exactly means having a female personality per say.
I would just call it "lesbian". You're a woman, attracted to women. Don't try to complicate matters by making a distinction between cisgender and transgender women.
Though I do find that the "traditional" terms for orientation tend to break down when applied to transgender individuals such as us. I thought a term such as "gynophile" would be appropriate, and not have any bearing on the gynophile's own gender identity.
