Why she doesn't cum from the intercourse? How can you unlock that?

I've discovered coding back in 2013 and three years later I spent all my summer building my first Laravel app which is still in production by the non-profit I've built for.
Now I'm struggling to find the balance between enjoying the power of "I can build this myself" and not chocking myself to death trying to build everything myself.
As it is common for developers to be less articulate, I decided to leverage writing about my endeavours, to keep me up.
Only minority of girls cum this way, once you give her this powerful orgasm, she's gonna remember you for life. But best of all, it's going to be the sexiest state of her you'd ever see. It is difficult to unlock this, say, level in the beginning but it's very possible.
Biology - we’re wired differently.
A woman's biology is something wow. The first time I read about it I was fascinated. But don't worry, I will not bore you with it. You only need to know two simplified key facts to dig into this question.
Clitoris is short of the female equivalent of penis, yet twice as sensitive to the touch.
Vagina, on the other hand, has different design and does not respond to the touch as fast.
That means, unlike as - guys, it takes a greater journey for a lady to reach a climax from within inside stimulation. Be it an intercourse, fingering, toys, etc.
Brains - they never chill
Plus, not biological fact, our brains work differently. During sexual arousal a guy is in his natural state to take the lead until culmination. He doesn't necessarily need to be assured by a girl, nor feel completely safe and trusted.
Unfortunately, when we flip the roles, a girl often doesn't get to feel fully relaxed. She is by nature thinking about a dozen of things. Mostly about how you perceive her. A bit fearing for things going wrong-awkward. But sometimes also about the things she had done during the day, haha. I know it sounds a bit funny but that's true.
There is one main thing to understand here. That, even if she seems and thinks she is completely relaxed, she likely is not. Especially if she hasn't known you for a long time.
Mental effect - power of peace
An interesting fact here is that it not uncommon for a girl to be a believer that she can only orgasm in a relationship. She becomes a believer that it works against her advantage if she's not in the mood for anything serious. I've heard this a lot of times, and I've witnessed this proven wrong many times too.
To be clear, I don't advocate neither for one or the another. I rather wish to call things by their real names. In relationship, a girl has it much easy to reach that peace of mind that allows her to be physically present. But with the right guy, any girl can feel that. To put this simple to understand, think of doctors you've visited as a kid. Some you had talked and felt stress build up each minute. Others you talked and it is as if he was breathing out mist of peace, you felt so calm.
I had a girl tell me how she would feel so calm in the presence of some men, that she would get dripping wet. That is, in not sexual contexts.
Can you really picture the power of that? Think for a moment.
Does the size matter? Yes & No.
Of course, it would be silly to ignore the size of penis. It matters and having a perfect match for each other can work wonders. But, this is not something we can change so don't worry about it. If you cannot give her this experience with fingers, it wouldn't matter even if you couldn’t fit in your pants. Likewise, the groundwork we can lay down is the cornerstone.
TL:DR; Reasons
This brings to 3 main facts playing against.
Biologically, her womanhood needs much more stimulation.
She needs to be fully relaxed and present, not mentally elsewhere.
She needs to trust you that you know what you're doing, in the sense of being a leader in the bedroom. Therefore letting her feel safe in your presence.
What can you do about it?
Many things. You need to know what you're getting into it and you need to have stamina. Whether it is your penis or fingers. I am planning on writing how to train to improve that.
Foreplay - focus how she feels
Then, lots of foreplay. It starts with the way you talk with her on the phone, to how you make her feel around you, or at your place. Long before you start taking each other clothes off.
Have dimmed lights, good playlist on. You want everything playing to your advantage.
After you do that, appreciate her body. Compliment from within your heart. It's okay to not be crazy about each inch of her and you don't have to fake it. It's the energy that matters, and if you didn't find her attractive you wouldn't be here. So reframe that energy and make her feel sexy and desired.
Being slow is your friend
Start with light, slow touches away from the peak spots. Take your time. The lack of speed is your friend. The longer you can stretch out going slow the easier you will have. This helps her relax and get into her body.
Going to one hour Thai massage makes this so easy to understand. Around 30 minutes in is when I realize my mind begins chilling down and I'm just relaxing and enjoying. Try it.
Once you get to her pussy, be prepared it's gonna take a while. Don't expect to succeed from the first try not don't make it about it as she will know and it will work against you.
I don't want to dive into how you should touch her in this post. My biggest lesson here is that making a girl extremely aroused and (close to) climax is what you want. Doesn't matter what ways you do this. This will unlock her ability to climax with you inside.
Explore her sexual fantasies
It’s more than okay to talk with her what she likes and inviting her to share her fantasizes. Unfortunately, it’s one of the most difficult things for many girls to do, I’d say guys too. But knowing what someone likes, you can really build that scene they want and this will add a ton to her arousal.
A simple example, I had a girl who always wanted to try something from bdsm and he had mentioned she never came with a guy. We did entire sexual fantasy exploration. That led to putting a collar on her, tying her hands behind. Starting with a rough play scene her kneeling down before me, dirty talking and spanking, followed by an intercourse. She was shaking and climaxing in less than a few minutes from the start of the intercourse. It was a very hot scene. It was led with knowledge, assertiveness and confidence.
In this situation the mental side of the things were very much on our side. She felt rather very stressed about it. We had gone for some shots and I was borderline letting her go home and she seemed like those students lining up before the oral exam in the university and close to switching colors. Yet she had a great conviction and desire to try, and the fact I was able to talk about all these things in a very peaceful and open manner made her feel safe. This is something that will come to you naturally as you grow and improve. Most importantly, prioritize to giving her a good time above you finishing.
Lots of options
By this point, you probably realize how much you can, and it's wonderful. Not many are going to do that, and when you do she will thank you for it.
