I worked in the adult industry after getting laid off from a full-time teaching job. I have to tell you that you should not be concerned. Unless your material came from an adult site then you should not be concerned.
Remember, there is a difference between art and pornography. For example, you can post pictures of naked children but you cannot post pictures of naked children in sexual situations. There is a difference. The one is something a parent took and the other is a picture taken by someone trying to make money on people into kiddie porn. The real issue is "pornography" not adult content.
