Curious about sexting within a relationship

My girlfriend sent me spicy text today. It caused me to think about this. I mean I think it has to do with the definition of porn in this community. If someone's in a relationship, do y'all think that pictures of the people there in a relationship with count? I'm personally not on a hard mode so I don't have a problem with sexually engaging with my girlfriend but I'm wondering if that extends to photographs and spicy text etc. I mostly just wanting to know what y'all think.
