I've seen a lot of posts where things fizzle/blow out over text game so I thought I'd throw in a few tips to help things along:
Keeping the momentum going in attraction is very important. A lot of this is due to timing... The texting guide advises you to vary your response times and if you have something else to do then do that first before texting.
This is good advice but it should only be done once you've built the attraction to a certain point. When you first get a girls number you should ping a few texts back and fourth to solidify the attraction. If she sends you a text and then you wait a few days before responding she'll assume your not interested and ignore it.
Think of it like building a fire, you have to be attentive in it's infancy then once you have a flame you can relax and attend it less frequently.
2) Boring texts!
The texting guide does cover this but it's worth re-iterating, the number of "how are you?" texts I'm seeing is frustrating. it's a boring text the more creative you get the better. It doesn't even need to be anything too clever just something interesting from your day-to-day life with a twist. e.g. "just walked into the wrong changing rooms in-front of a gym full of people... massively embarrassing!"
cliffhanger texts work well as a re-engage i.e. "omg just had the most embarrassing day ever!" but only use them when you have attraction built.
3) Needy Texts
I don't just mean the "I miss you" kind of thing. That should be a self-evident no no. I mean the texts that confer beta behaviour. For instance, "we never got to have that drink" or "how comes your left so early?". These confer neediness, also asking a girl to kiss her "can we kiss?" (yes my friend actually said that on friday) should all be confined to the dark recesses of your mind and they should stay there!
There are two problems here, going graphic too soon and not spicing things up at all! Obviously you want to fall in the middle. I would encourage you to push things in a sexual direction as it's much better to try and fail than to never try, plus you can always just apologise and backtrack if you go too far. The trick to sexting is to build to it slowly. Start with something small, i.e. tell her you'll give her a spanking if she's doing something you don't like. Or offer a back rub anything that implies sexuality, don't say - imply. This leaves you room to back out and blame her dirty mind if you go too far.
These are all fairly basic but I figured it's always good to remind ourselves what NOT to do.
