I have been working on maintaining eye contact when I walk to someone or just when I am walking down the street. I have seen some people here say that a good method when looking a girl in the eyes is to make your intentions known through that contact. Visualizing sex and stuff like that. I seem to be hitting a block completely in that. I can hold the eye contact well enough during conversation but I have no idea if I am sending out the right signal or not. Is there any beginner steps to this visualization or should I keep working on basic eye contact?
