Porn isn't just fantasy for the viewer, either: just like actors in movies who play FBI agents often aren't and don't want to be FBI agents, actors in pornography are sometimes not the sexual orientation in real life that they're portraying on-screen or in photographs, or aren't really into what they're acting like they're into in a scene. A big part of viewing, reading, or otherwise engaging in fantasy is about escaping reality, or exploring thoughts and feelings that maybe we think we might like in reality, but which aren't actually realistic or possible, aren't possible yet, or which we don't feel would be safe or comfortable for us in actuality. That's often particularly the case with fantasy media, which pornography usually very much is. What a person wants and enjoys in media - including pornography - may or may not have any relationship to what they want and enjoy in real life.
