I am a biological boy but I am trying out being trans/bigender I have now started going by she/her pronouns but I keep misgendering my self does that mean I am not trans/bigender?
That is SUPER common at first! You're so used to saying one thing for yourself, you just need to kind of get used to addressing yourself differently is all
Relax, don't worry about it - it happens to loads of us. I'm more than two years in from my own gender revelation and today I sent an email with my old name on it!
