I'm trying daygame with the aim of finding a girlfriend, and it has been hard to say the least..

It seems that girls think I'm a player, even when I'm not teasing them or using any game, just talking normally and trying to get to know her.

Is it because I like to go for shy / nerdy-looking girls? They are really my type. But how do I go about it without saying "I'm looking for a relationship, not just sex" ?

How do you personally overcome this kind of issue?
