You know, if Lucas had wanted to, he could have worked it so Anakin has at least one affair. Maybe with Ahsoka, maybe with some other woman, but the idea that he would sleep with another woman is interesting. I can see him doing it and still, nonetheless, being obsessed with Padme's purity and beauty. It would make him a hypocrite, but you could incorporate that into his fall to the Dark Side. The idea that he expects and demands so much from the people he's connected to, even as he makes excuses for himself and his own behavior, is a potent one.
The way the prequels and EU went is also good, but I think this other direction could have been explored.
