Oh, sorry. How old are you mate? Perhaps I was too lucky with my mom when she let me bring girls home

It didn't really come off as needy, it just seems like you didn't want to take the risk. You thought it was too soon to kiss her... Was it though? How could you know if you hadn't tried it? Believe me this: you should have tried to kiss her, and even if she rejected you, saying it was too soon, it would have been far far away from a lost case, as long as you handled the rejection with cool. (eg. something like, "okay... I just thought you were up to something

")
Now other things. You didn't know her age, or anything about her. What were you talking about then, if you don't know anything about her?
Text game. I can't really say much about this. I rarely do any text game, because usually I just use the number to fix a Day 2. Probably I send her something funny that happened with me or just something that will get me in her head for a few hours. Best if related to something that I used to build some connection. For example I like to make up funny nicknames(of course not overdoing it, and only if she seems to like it. not every girl is into this...also...not cheesy, but funny nicks) and I call them that way in my text. To give you a clear example:
Situation: girl with santa hat. K-closed, after that #closed, gave her the nick 'Santa'.
First Text I sent(if I remember right 2 days later): "Hey Santa, I really hope my presents are on their way..."
She replied: "Haha no way I'm giving you anything. Only good guys get presents"(shit test)
Me: "Sweet. I'm free on the weekend, I was planning to go play pool. You should come too."(ignoring shit test completely, and getting to the point)
After this we fixed a date I fucked her, but we couldn't really connect so it was over at that point, really nothing complicated. I'm still in a good relation with her, maybe I'd even bang her sometimes if I didn't have a girlfriend at the moment
See the point here. I was playful, not needy, but I was moving things forward. Of course I'm not some pick-up genius and I fuck up regularly too. But that's why it is important to not get stuck with one girl. As long as you're not in a committed relationship, you should NEVER focus on only one girl.
