EDIT: Girlfriend WONT show me her YouTube channel.

Hoping to get some insight here on whether or not I’m being irrational. A couple months ago my (M24) girlfriend F(20) decided to make a YouTube account and create ASMR content. She posted her first video and I asked if I could see it. She refused to let me watch and said she feels uncomfortable because it’s the content is weird. I get it. But here we are months later, she’s posted many videos now and is starting to get some subscribers and I’m feeling weird about her not allowing me to see her channel or any videos. Today I expressed that I am having some anxiety about it and it makes me feel less close to her and our argument started to get heated and we both dug our heels into the sand. She is now calling me controlling and saying I should just let her have this private thing. I am saying that I am not comfortable with it and think it’s super strange to have a secret YouTube channel. What are your thoughts. THANK YOU
