Guys do you like confident girls? Watch
Shy girls are actually quite annoying in relationships because you always have to second guess them, even when you're comfortable some of them still repress what they feel, the result is you both end up frustrated.
I can testify to this. I'm a shy girl and although I'm told often that I'm pretty wherever I go but no one has ever been interested in actually having a relationship with me. I'm working on turning it all around though.
