Deep (kind of... not really I guess) thought

So... it's a Saturday... I have the day off from work... I live in midtown Manhattan and I am bored and confused. I am definitely not depressed, but just not content. I am thinking that I don't possess the flirt jean. Every girl I have ever encountered (that I realistically would have a romantic relationship with) has wanted to be good friends. I don't think I'm gay. I'm just romantically challenged I guess. Who knows? I'm attractive (not to sound vain) but I am. I'm not ugly by any standard. I'm 6'4 and slender, not too skinny,just normal,but I have a great face with good bone structure. So it can't be because I'm ugly. I guess the main factor is my shyness and possible fear of rejection? Well, there it is, I know the problem, if only it was that easy to stop being afraid of rejection. I'm very outgoing, and no-one that casually knows me (co-workers, etc.) would categorize me as shy. I'm a secret shy, relative to the environment. I just want a relationship.
