im confused about asexuals.

so when I learned about it it was the animal way, but then it became a human thing and then learned about the original way that people who are asexuals don't get the horny feeling and guys who are asexuals don't get boners. and there was so many different ways like some asexuals will have sex like a chore thing and some can only get off by touching themselves sexual or not and some only date other asexuals and never have sex. but now that it's popular people are changing it to like I'm asexual but I like to have sex still and almost everyday. but that's not the origin of it 🤷 and then they fight you like your going to steal there title from them. don't get me wrong you can label yourself whatever you want but don't forget the original meaning behind it.
