no guts

Oh, you know we are not all the same, some of us are way more easy-going and approaching to girls doesn’t seem to be a problem to them. On the other hand, there are the people who are too shy and reserved and even communication with the people of opposite sex is making them nervous and like they lack self esteem. I always think it’s the best solution to be in the so called “golden middle”, not moving too fast forward and not being totally laid back when such situations occur.
In your case, as you already don’t have problems talking to a girl, you will have to work a bit more on other aspects of communication, the ones you think you will need if you want to win a girl. What exactly is your problem? When you say that you can’t move anywhere from the conversation, do you mean on sex or what? If so, you know that, assuming you really like the girl, conversation is what matters the most at the beginning, then everything else comes spontaneously, so you don’t worry, when the right girl comes you will surely find the way for everything!
