neobrood... you're asking the wrong questions... The fact is that you are always either progressing or regressing, you have to continually escalate things... slowly, or rather as quickly as she is comfortable with... and the only way to figure out how comfortable she is is to continually make "moves".
Let's just say, you are waiting for the bus and you see a cute girl, you start a conversation, and your bus comes, quite likely the only 'moves' you could make would be to get her number. Let's continue to say that you get this girls number, you call and get a date, on this date the conversation is going well, and as you walk you put your hand on her waist, providing she is comfortable, you might escalate to a kiss, to making out, but then have to stop there because any more would make her uncomfortable.... and she will let you know if your going to fast.
I've went from meeting a girl to sexing her in less then 2 hours, but I've also dated a girl for 5 months without doing as much...
Then, on the next date, you could start with a kiss because you had already gone further with her, and just continue from there. There is a lot of common sense in this... and when in doubt, go with your gut.
