What stuff?
And of course it does not exclude the possibility of consuming porn (The only situation that does is not having internet or TV). But I don't watch porn and I don't think I need to given my current life style and personal principles. As simple as that.
Stuff, as in, why people watch porn and what it means.
I'm not criticizing you in any way for not watching it. Doesn't matter to me. I just think it's really odd to drop "I'm in a very healthy relationship" into this conversation, as if that fact by itself means you don't consume porn.
