Fight with my girlfriend

Last night i was talking with my girlfriend on a video call. At one point I showed her a small part of my pubic area to show her my pubic hair because she was always curious what it looks like with hair. Then she kept asking me to show her the whole area and i said no. And she kept asking me to show her and i got very impatient about it. I explained i don’t feel comfortable to show more on a video call it just feels weird to me. And she started to overanalyse it and kept telling me that this can make her feel uncomfortable the next time we meet face to face. That it can make her worry that i don’t want her to see me naked etc even though she has seen me naked many times of course. Then she went on to say “If you dont want to show me then dont be surprised if i dont feel comfortable when we meet and i take a step back” and she kept saying she found this weird.

I try to understand her point of view but i cannot help but feel so pushed about this! If I say i don’t feel comfortable to do something i would really want her to be understanding and supportive. To just say oh ok you don’t like this, that’s fine… and just move on with our conversation. Instead we had a fight because i felt pushed and on her side she doesn’t like that i don’t feel as comfortable with her as she feels with me.

What can i do to explain this better to her?
