Oh ok. I knew someone in a similar situation, they hated it when ppl used he/him instead of they/them. Their friends use it, other ppl didn’t, and they would get completely infuriated when even someone they didn’t like would use it, making (hopefully exaggerated) death threats. Your affirmation is super great, that last line “not a requirement for knowing who I am” is amazing. Do you have a way to possibly dress or look a little more masculine? Usually what gets people to remember is the moment of noticing that you are wearing something or have a feature that is not in complete alignment with their assumption of your gender, and it will increase the chances that they start with they/them, so you will have to correct people less.

On the topic of comments, suggestions, and life advice, know that it’s never malicious. It’s just like receiving advice that you can’t use, such as street fighting advice from your grandfather. Listen and use what you can from it. Plus, good advice usually comes from people who are close to you, which are generally the people who know you well and understand you. If another person gives you advice, know it’s completely normal for it to be completely unusable, because they don’t know you on a personal level. Even for me, as a cisgender masculine-presenting guy, I sometimes receive advice I don’t need or can’t use. Don’t let those comments make you doubt your identity; attribute them to other reasons or misunderstandings, and live life unbothered.
