I think that changing your name is wrong, it will be harder to find and identify you. Most often they create a double with nsfw prefix

Something like that too I thought, mainly I just don't want it to be very obvious that it's me haha, maybe some prefix or added but no directly the word "dremet", more than anything to avoid problems if family or acquaintance gets to look for that name and well that content comes out

I think you shouldn’t worry about this, it will be easier if they find out about it someday.
The fact that you are on FA already says something ~
It’s unlikely that someone you know will find these works only if they don’t do it on purpose. But if you are very worried you can use a different name there. Again, there may just be confusion.
