At what age did you realize you were merely a tool for someone else to get off?

I’ve learned that it’s easier to understand the physical aspect of being sexually abused in any point of time (in my case much younger ( early twenties)but the mental/emotional abuse from family or people close to you who keeps getting off on you every single day is inexcusable.

Even knowing you’re a tool for them throwing those mental shit on you and still you can’t react the way you’re supposed to just because…
