Hey! Silverdrake, don't worry about it! Just take it slowly.
I never really hard a girlfriend period, but I never really wanted one so I guess that's why. I don't think I ever thought of not having a girlfriend as being a problem though. But as far as advice goes well...
Just be yourself. Now, obviously, I don't you'd actually go and pretend you're some completely different person (this is the Real World, not a Soap Opera ^^). But just stick to your opinions and stick to who you are. If the girl you're courting doesn't like it, well, either she accepts you for who you are or just give it up. If a girl can't accept you for who you are, then the relation will not last long.
Closely related to being yourself, just stay calm and cool if you happen to meet the lady of your dreams. The last thing you want to do is to get tongue twisted and then have no idea what to say or what to do because you're so nervous. Just be calm and yourself. That's what I go by.
Third, don't rush it. If you're going through the place and no girl seems to even look at you, don't go looking for a girl for the sake of it. These things take time and it takes practice. If you don't seem to be able to find one, don't get down and start saying "no girl likes me..." and all, it just takes some times.
Now after all the don't do this and don't do that, for something different, do sweep her off her feet when you meet the special her. ~_^
