I always masturbate to the same picture of an actor, iin?

I'm a girl and even when I had a bf, I couldn't stop masturbating to a certain actor's picture. I keep it as my ipad background, so it's very convenient. It isn't even a sexual image; he is fully clothed and smiling. No matter what, it's always him. His smile makes me weak and I imagine doing the dirtiest things with him...no one else, not even a real guy can get me off this way.

Oh, and he usually portrays sociopaths, so that adds an awkward level to the story.
