Again, it is all relative, even touching. You always have to be ready to go to 100 otherwise you'll mess up a lot, and at the same time you should expect her to hit brakes at any time.
For example, you meet one girl and go for Date #1. You are ready to go to 100 but she puts brakes on at 40, you get stuck. You might think that at Date #2 she will go to 60, so get yourself ready for 70. But what you don't know is that she might be ready for 100 at Date #2. She just wasn't ready the first time, she didn't expect such a quick advances, but now she changed her mind and got herself ready for Date #2. If you are not ready for 100 at Date #2 you screwed yourself up and you stopped at 70. She may perceive you as hesitant guy and she will dump you. No Date #3 for you.
You meet another girl. You think she may not be ready the first date for 100, so you are thinking you will push it till 70. She gives you resistance so you gave up at 70. But she was ready for 100, all you had to do is to push more. Then you go for second date and you think that you might push it till 100 because you almost had her last time, and you are thinking she is ready. But now she is ready only for 30, she hits the brakes at 30 and you are screwed again. She will dump you because you are advancing too fast.
As far as touching, here is some example. First, you got to have great fundamentals. Great Fundamentals generate great attraction. You have a good posture, you are relaxed, you are positive, you are "open", you are confortable and confident. This is important, because she scans you and she will mirror your attitude. She can simply feel those things. She will feel the same way like you do, which is good. If you feel good, she feels good, and she perceives you as being attractive - she comes closer to you, approach you.
Note that I am not talking about you going after her and requesting a phone number from her, this is the opposite when she makes an effort to get closer to you. I'm not saying that approaching girls is wrong, it is just more effort, whereas when she approaches you first you already know that she likes you and she is investing into you. You simply eliminate a lot of headache and rejection, but at the same token you may lose some girls who are shy to approach a guy.
You go for a date, she is excited to meet a new guy, you feel good about yourself - she mirrors you and she feels good about herself. You don't talk about yourself, you talk about her. You don't say nothing about yourself, only the minimum possible.
You talk about her. She starts talking about herself, things she likes, things she does and so on. You like what she talks about, why wouldn't you like it? The things she likes comes with her pussy. You like pussy. So you are simply interested about what she does, you ask her natural questions so she talks about it more. You like some topics more, so you talk more about those topics. You like other topics less, so you don't talk much about them, you switch the subject. There you go, this is your deep diving, simple and easy, no headaches.
There are of course different boring topics, such as boring questions about you. But you don't want to be boring so you always and gently reflect those questions to something else. For example, she ask you if you like to travel. "Yes I like to travel, and I know this guy who's been with me to Paris, and he met a girl there, he hooked up with her the first day and ... blah blah.... Do you like to travel?" And now she's got to talk about herself again.
Congratulations, you've just avoided first rejection by not talking about yourself, you are still this mysterious guy who she knows nothing about. Now she's got to work harder to find out who you are, she's got to invest more into you. That is challenging for her, she has to find out who you are because you are not boring like the other guys she knows! Not only that, now she also knows that you have a friend who can hook up with a girl fast. Fast hookup, exciting! And she knows you've been to Paris. How romantic!
So, the reason why I'm not just talking about touching here is because the underlying emotions/vibes are also important. She needs to feel good, she needs to feel some excitement. She needs to know that you are interested in her, and if she has to talk a lot about herself it makes her feel good.
With the underlying emotions/vibes things are easier because you don't have to think much and you don't have to look for clever ways to get her to bed. She simply feels good and she wants to feel even better. Again, this should be your fundamentals.
Now back to the touching. Say you are walking with her through the town, and she is brushing against you here and there. Good, that is a first physical contact. You then stop on the bridge, and looking into the water, your arms are supported on the railing. She is close, ideally she invades your space (Why? Because she feels good!), and she kinda leans against you, touches with her body side of your left arm. Good.
She is talking, so now you can touch her jewelry, talk about it. She likes it, touching continues, you can put your right hand on her left forearm. If she doesn't pull away (and again, if she feels good she will not), you can continue touching. Say you can put your left palm on her lower back gently, and move your arm around, slightly up and down. Does she like it? Good! She still feel good.
Then grab her left forearm more firmly (you are pushing forward). Still like it? Great, well, be more firm with your left palm on her lower back and at the same time turn your head closer to her right cheek, as if you are attempting to kiss her. Your lips are perhaps 1 inch from her cheek. Should you kiss or not? Your choice, maybe you can just say something about how her hair smells good. If she is still like it (smiles, blushes), you can push further. How about turn more towards her side and gently touch her thigh with your dick?
Oh! That is too much for her, now she pulls away, her brakes are on. I know you want to fuck her right there because you are so fucking impatient and your dick is tingling, but hold your horses for now. She is not ready yet. She just went from 60 to 40. No big deal, that was expected. Cool off, and lets go to the park then! You are pulling back, you are slowing down, but make sure she is still feeling good, let her talk about whatever she wants to talk. Don't get discouraged, don't get upset otherwise she will dump you. Go back to fundamentals - you feel great, you are relaxed, nothing happened, you are just having fun.
Sit on the bench. She is still vibing, good, so put your left arm around her shoulders. Some talk. Looking in her face again from close distance. Quick kiss? She just giggles. Right palm on her thigh gently, closer to the knee. But she pushes away. Ok, hold her forearm then. Just for a couple of seconds, and then again on her thigh. Now she lets you to keep your hand on her knee. Good. Give her a quick kiss then, squeeze her shoulder with the other hand. Say something and move your hand up her thigh, closer to her pussy. She just puts her hand on yours so you can't go further. Who cares? You are almost touching her pussy through the clothes.
Ok, you are stuck again. Maybe something totally spontaneous, totally stupid would help at this moment. Hey, there is a lake, why don't we just get naked and jump into it? She just laughs because it is stupid. You can't get naked in front of others and go swimming in the lake silly, you just don't do that! But now you give her a good kiss, and she is kissing back. Ok, now you can touch her neck if you insist.
Kissing a while? Touch her stomach, gently, move up and down. Try to touch her tits. She won't let you? Alright, lets touch her pussy then. She just pushes you away. Awkward moment, it is quiet for a moment. Take a breath, let her talk about something, pull back a little. Make sure she is relaxed.
Hey, how about more stupid things? Doesn't know any? No big deal, just stick your tongue in her ear, watch her to burst out laughing. Stomach again, this time your hand is under her shirt. She pushes your hand away, just to find out that now you are touching her wet pussy.
Oh, this fucking guy! He is just relentless, nothing will stop him! Let's walk some other place, it is just too much!
So you are walking, just talking casual things. You are not discouraged and you remain in good mood because nothing happened. You are touching her back again, you stop and you give her a good hug and a good kiss.
This fucking guy doesn't really want to stop! But now she is getting really nervous.
She is got to make quite a decision now, the most difficult moment for her came. She only wishes he doesn't talk about getting into his place, so far she likes everything a lot, he is exciting guy, but she is not ready for sex.
But he does ask her to go to his place. Her excitement/nervousness just shoots through the roof, and she is ready to walk away. Why can't this guy just stop here? Wasn't everything great so far? Why does he need more?
I have to go home, she says, it is getting really late. Of course, you say, let me walk you. Good, she is finally relieved. She checks her senses again, she feels that you are still in positive mood, totally relaxed, acting as if nothing happen. She calms down, gets less nervous. You are now holding her hand, she is getting relaxed too. But wait a minute, where is he going? She lives the other direction. He is headed to his place!
But she can't really think much because you are hugging her again and gave her a good kiss while rubbing your thigh against her pussy. She doesn't know what to do, she has no idea what she should do. Why not follow then, he just leads so strongly, he doesn't hesitate one second, he is so calm and relaxed, he just knows exactly what he wants. He wants her, and her pussy is already wet. After all, all this touching just feels so good...
