Running a routine for the kiss is one very good way to make it creepy actually
I don't like routines. I've tried them. They fail. They can get you to a level but not farther.
It's a lot more effective to react to the vibes that the woman sends you. It's a natural feeling you get, pretty hard to explain but I remember being the complete wbAFC long ago, even then I could feel it. When there are sexual vibes, every human being feels it. You can even feel it if you just watch people flirting, of course it's a lot more intense when it's you and a girl flirting with each other.
Throughout the interaction this vibe is of course not constant. It fluctuates. And when I feel it is coming to a peak, then I sneak in some touches, some hugs to get the maximum out of these peaks. It sounds weird but if you just touch a woman's arm slightly at the correct moment, you can make her dripping wet! When I feel like I have teased her enough I will just go for the kiss right before another peak and that's it. But take note that I don't really think about these things anymore. It's by the way fucking hard to do it when you're thinking about it because then you have less concentration to actually feel the things going on.
This is pretty much the natural way. Natural game operates with frames and vibes rather than routines. I found it a bit harder to get the hang of it, but once you have it, everything becomes so much fucking easier from the opening to the close throughout the entire game.
The key to understanding these vibes is practising. Practise, practise, and more practise. Open sets, and flirt with them. Flirt only verbally, flilrt only non-verbally, flirt ruthlessly, flirt in just a friendly way. Experiment. It's pretty fun to do it when you actually look at like this. "I'm not trying to pick this chick up. I'm trying to improve my flirting skills". When you're not trial-and erroring with routines, rather with specific skills, that you need to better, it's a lot easier to improve, and actually a lot more fun too, for the reasons I said earlier.
This is why I said you need experience. You need to learn a lot. It's simple logic. If you don't know how to drive, how are you going to win a race? If you can't even kiss a girl, how do you want to keep her as a girlfriend? Same thing, sadly. Go out and start practising. It's really for your own good. You don't need to become a ruthless player. I'm not like that eventhough I could be if I wanted. For the last 2 years, with very few exceptions, and not taking the "learning material girls" into consideration, I have only gamed my LTRs.
