What does it mean when girl says she's addicted?

My girlfriend of almost three months now has told me a few times already that she's addicted to my dick and having sex with just me. Does this have any deeper meaner usually? As in she's hinting that she wants this to be a ltr or that she loves me? Or does it simply just mean she sees me as a sex tool and that I'm really just there to satisfy her sexual urges?
