does it still mean you're straight?

I'm a girl •-• but my question is, if I were to do a sex change and become a guy but still want to do it with a guy (okay with being uke or seme) does that mean I'm gay to societies eye e.e and still straight somehow cuz I know I'm not into girls. But if I were, would that still make me a lesbian XD even if I physically appear as a dude to society which would make me straight but deep inside I'm still a girl?
