This shows you the importance of a good sevivah (which is another whole topic)
But now that you find yourself in that situation, you have to work doubly as hard to keep/regain your sensitivity.
At least when you are not at work you should associate yourself with people who dress the right way, and you definitely should not expose yourself to the secular media (videos, magazines) because if you compare yourselves to them, even the most untzniusdike skirt will seem very modest!
