Sexting is important??

Soo hyy i(20M) and my girlfriend(20F) are in a very happy peaceful relationship even though we're in a long distance relation everything is fine. But she always asks for sexting and all but idk I'm not that into it, I can't put into words and that doesn't mean I don't want her sexually or I'm not sexually attracted to her. But she feels that I'm not sexting because I'm not attracted to her. I tried explaining that it's just that i can't put it into words and i want to everything like literally everything with you but still she's upset. And once i explained everything she blamed herself but there's nothing to blame here, she want's that and I'm not into it 🥲 and i want to change
