That reminds me of an old Zen Buddhist story. Two monks, an older monk and a young monk, were walking toward the shallow of a river when they noticed a young lady there, upset, stuck and confused on how she was going to cross without getting her ornate clothes and belonging wet. As they approached, the young man began to hesitate slightly, slowing his footsteps. Mean while, the old monk continued steadfast toward the young lady. Without a word or a hesitation, he picked her up above the water and carried her to shore on the other side, with the young monk hurrying to catch up and trail. When they it to shore, he sat her down and they continued on their separate ways.
For over 30 minutes, they walked in silence until finally the young man burst out, "Master, how could you put your hands on a young lady like that and carry her! People would see that as improper!"
The master replied, "I put the girl down all the way back there on the bank of the river. It is you who still carries her."
One of the visualizations Buddhists learn is that when they have lustful thoughts about a woman, they are supposed to do just as you described; visualize their body as it truly is, in all it's indecency; excrement, urine, bile, intestines, organs, a grimacing skeleton with huge round eyeballs, all of it. It removes the mystery which kills the fantasy. This is why women make more money when they don't get naked, and why porn stars save anal for when their career is dying.
