Keep in mind, these are IT guys. I usually have to remind myself to look in someone's eyes when talking, be it man or woman. If I'm focusing on something else when someone is talking to me I might not even look at them at all.

From what I've read about the differences between men and women, women are MUCH MUCH more likely to pick up subtle body language gestures compared to men and try to analyze what they mean. Try not to take these things personally. Many times it might not even have anything to do with you.
