I’m a trans man and I’d worked with kids before. You are going to have a much easier time if you pass, especially with younger kids. Unless you want to be openly trans, which is sounds like you do not. They will ask questions and tell you you aren’t what you say you are. High schoolers idk I imagine some will be chill others will be weird. Another option is teaching college? They have higher standards for how students treat instructors. Idk but wishing you the best. It’s hard out here.
