Infidelity and mass media

Getting caught in bed with another man has got to be scary.  On the other hand, men should never sleep with another man's wife.  Women should also be more faithful.  I have had sexual thoughts and images that coincide with what I am writing today.  There are videos about this and I see it on tv shows and movies. Those images and thoughts are scary and they won't go away.  I was so anxious last night as I was posting music videos on one of my blogs.  I was tempted to watch another video but I was only tempted.  Should I as a Christian watch or be overly concerned about what I should see on television?  Should I stop watching television altogether?  That is quite hard and I wish I had a definite answer to this one.  Mass media is another OCD issue I have had for a number of years; I have been avoiding much of mass media for a while now because I am afraid that something will trigger another scary thought.  I am afraid that someone will commit infidelity or get caught committing infidelity.  Maybe as a Christian I shouldn't watch those scenes, but I am also confused.  It is as if I am allowing the OCD to dictate what I should watch or what I should listen to.  That also scares me.  I wish that I had a definite answer too.
