Triangular Gazing is a gaze that people who are attracted to each other do. It is usually when your gaze shifts from eye to eye than down to the lips back up to the eyes, making a triangular shape with its base at the eyes. It actually increases attraction sort of. Its a subconscious thing people do, and I find that if I do it to a woman she will start doing it too.
I like to do it to all women that look good and it actually does something.... I dunno how, but things I have noticed is that it makes you look like you are analyzing her face... making you more attractive. Try it.
