Feeling weird explaining to other people that I use AAC and add my own stuff to the board.

[whole thunder]

For context, sometimes I have speech loss episodes with my FND, and I have recently added myself back to WeaveChat, a free AAC app for my phone and tablets. But because I can, I add my own phrases and words myself to better communicate, and some of it is kind of controversial, like cursing or other things my app doesn't have, like a word for some of my sexualities. But like I feel so weird explaining to people that I, a LSN autistic, has this on their phone. How do I explain it?

For context AAC stands for Augmentative and Alternate Communication

I can verbalize fine, but with FND and sometimes slight difficulty with words, it might help to have it
