You have asked this exact question many times.

You are you, the grass isn’t necessarily greener on the other side. Seems rather unlikely to reincarnate in the past and I doubt you'll be your non-existent twin sister. Perhaps you'll be a girl in a future life though. I don’t think we can help here, sounds like you look for some non-existent ''spiritual technique'' to make it all happen. Sounds like fantasy. Maybe a professional psychologist can help you understand these desires you’re having.
