Oh no poor Little! That bites. How embarrassing. But yeah it sounds like it wasn't that bad of a text or too much personal information. And I think BF replied in a friendly way and you were able to joke it off. So that part of it shouldn't be too embarrassing.
We all have these moments where we make a mistake. At least it wasn't worse, where you were complaining about someone or accidentally sending out your BF's naughty video to everyone you know.
