It depends, after reincarnating do you retain your memories of your past life? Do you think of yourself as a girl, boy, both, neither, fluid?
But with how you're describing it, where you have sexual and romantic interest for others of the same & opposite (or just different) gender as you, you are most likely bi or pan.
Remember, gender is what you identify as, and sex is biology.
Look, if I (female) die and reincarnated as a guy then I feel in love and do lovey dovey thingy and censored scene with female lead, does it mean I am gay? But wait a minute... Since I was a female I am also interest ed in male as well ... Does it mean I am straight?
