CS Lewis' in 'The Screwtape Letters' talks about the way that sometimes God does give us rest from our persistent temptations before they return as before, so obviously your experience is not unique. Actually in my own experience recently, whilst I was staying for a few weeks with a family, who had a couple of boys whom I didn't find especially attractive, the routine experience of being in regular and high quality contact with other people coincided with a trough in my temptation. Now I'm back living on my own the struggle has resumed - though the hiatus was helpful. And I guess that's my present best advice: find ways to spend time with people in real relationship.

Sadly however that's not easy in our modern society - quality relationships are in short supply. (One lesson Mormonism can teach the church). So the other approach for me is distraction; going 'head to head' with a temptation is to lose - we need to find the way to 'escape', as the bible promises. Keeping busy and focused on good stuff can be helpful. But the best answer is about looking to Jesus when temptation comes knocking; we need to make that our habit. Easy? Of course not...
