Most Helpful Guy
It's not creepy -- as many guys have said on many answers, men RARELY see women as "creepy". That is a gal thing. It does, however, give the impression that we're somehow something to be avoided. That's how I feel anyway. If a girl refuses to look at me I start thinking that I'm creeping her out, or she doesn't want to talk to me and is waiting for me to figure it out. If she looks at me but just won't maintain eye contact, I assume she is shy.
If it's something you want to work on, I would suggest first focusing on looking someone in the eye while they're talking directly at you, and likewise looking at them when you're talking directly to them. You don't have to stare, but if you concentrate on the person you're talking/listening to you'll become less and less uncomfortable by eye contact. It'll cease to be something which should be avoided, and instead become something natural in everyday conversation.
Takes time, but it helps.6
