That was a question that I had. The definition of porn basically can be any picture or video i guess that is designed to promote desire. Doesnt even have to be nude by definition.
I do have some naked pictures of my W though that I have questioned whether or not that would be porn. I hear that it is very unhealthy though to use those at this time for me.
