I have to force myself to make eye contact, but can't when I'm really angry or upset with the person. If I'm not making eye contact because the conversation is uncomfortable, I usually consciously think that I have to show them I'm listening at some point, look them in the eye and try to look engaged.
The only time I find myself spontaneously seeking eye contact (other than intimate moments--and I don't have those anymore) is when I really am having trouble understanding what the person is telling me, and my mind is spinning a hundred miles an hour on the facts or a concept that lost me when I should be concentrating on the feeling or gist of what the person is trying to communicate.
I find the eye contact overwhelming at the time, but it helps me deconstruct the conversation later. I can better read the feelings behind the words (given time and space to work that out), if I've looked in their eyes at key points. During the convo, though, sometimes it gets too intense. When it gets too intense I have to remember to look away, so I can follow the words.
It's easy for me to get stuck in either input, so I try to walk this tightrope all the time. Also, I don't want the person to think I'm shutting them out or down when I'm working really hard to follow them.
