Do guys just like attention from girls for no reason?

I often wonder if there are just two types of men out there. Ones who once they are in a relationship they are completely contempt with their one girl and stop talking to any other girls either completely or not as much (if its a close friend), Then the guys that don't ever seem to know what they want that seem to seek attention from girls all the time, even if they are interested in someone. It always seems to be the guys that appear really secure, but I wonder if the constant attention seeking from the opposite gender means that they really aren't that secure. Is it possible for this type to have feelings for multiple people or are they really close off from everyone? Men confuse me so much...Why can't you be direct!
