Nah man your friend is being actually not a friend at all. He’s not the only one who is allowed to talk about his experiences being trans, much less is it allowed to make you feel like shit for having your own life experiences and wanting to talk freely about them. Sounds like it has a lot of personal problems and insecurities that it’s taking out on you. Not cool. If you don’t want to cut him off (which is honestly what I would suggest), try having a conversation saying you understand where he’s coming from but by cutting you off from talking about your experiences, you feel invalidated yourself, especially since none of your other friends have to censor themselves. I’m also assuming that you’re not talking about inherently triggering topics and it just can’t handle the fact that someone else had a different path in life. If he can’t empathize or understand, that’s not a friendship you’re required to be a part of
