Hello,
Let's get started. I created profile on Badoo, in my country that is used the most. Simple profile, I put that I want to make new friends, about me was like biography, interested in - normal girls, with feeling, blah, blah :vomit... I tried a lot of opening lines of all kinds:
1. "hi, you are cute, what's up?" - no results
2. "hi, I like you, would you like to have sex with me" - got some answers, and my profile was viewed a lot of times, but nothing good came out of there.
3. I tied something individual, and PUA-like then - "you seem like intelligent and independent person. I have read your profile, and I think you are somebody who is charming, you have your own opinion and you don't care what others think" - here I lost much time, I got some more responses, had 2 dates in 2 weeks, but I still wasn't satisfied.
Note: each one of these sentences were tested about 150 times
Then I started to make some changes. First I changed my profile. Added some good looking photos in interesting situations - me on snowboard, me partying with one girl licking my cheek and the other kissing me, me on the pool and so on... Then I changed fields "About me" and "Interested in". Somebody can get the idea so I will write it down for you.
About me:
I'm 23, I live with my mother, father and brother. We don't have any children. I've been through a lot in my life. I have ambitions too. The main goal for me is that when I grow up to be retired.
I am tall and very handsome. Always the most beautiful in the line when we get lined up by the police. There is no fat on my body, especially not on my stomach. Okay, maybe a little on my stomach, but I can run the whole circle around the court.
Semi-intelligent, open-minded, friendly, I can break the ice so I often clean snow in front of my building.
I play guitar and I know almost all the chords. In past life I played the triangle, so I continued in this one. I was really good until they told me, after two years of playing, that the triangle is not a wind instrument. Since then I am completely lost.
Among all fruit I eat chocolate the most.
Sometimes I am hard to understand, but it's very easy to love me.
I work part-time as a stuntman. Surely you've seen in the movies when the handsome actor has to show naked ass. Well, that's my job ...
Interested in:
It is desirable that a person is born in the year of pig or rabbit. Just kidding, age is not essential, but it is desirable that a person have most of their teeth.
If you often use one of the following sentences:
"I'd love that!"
"Why not!"
"I want the same thing, I was just embarrassed to ask!"
"What do you want me to cook?"
"我 想 吻 你, 我 宝宝"
... we'll get along fine.
If Paris is your favorite city, choose a wedding ring...
They say that time of gentleman has passed, that girls are now dominant, that they usually approach us and start conversation. I say that time has not come yet. We are the same in many ways, but not in this one. I'm here to prove it ... Therefore, do not send me a message first, wait for me to send it to you
Also I am looking for inspiration and ideas for my new, third in a row, book that I'm writing. If you are inspirational and you have a good idea, we will share the profits
Now, that being done, let's move to actual routine. It is important to have a strong profile, so if you don't change it first. You don't have to be good looking, just take pictures in some interesting situations.
The first message:
Hey, what's up, how are you? What works better for you - Monday or Wednesday?
- THAT'S IT! THAT'S ALL! STOP WASTING YOUR FUC*ING TIME! This way you will filter out all the girls that just want to chat and never want to meet somebody. I promise, you will get a lot of replays if you have strong profile. My respond rate is about 80%.
Now, there are 3 possible answers:
1. She says Monday. This means she is ready for sex very fast. Also she can be flaking! So, the only important thing to do in this situation is
NOT TO ASK FOR HER NUMBER/SPAM/WHATEVER IMMEDIATELY. Say, ok cool

. And then write at least 4-5 sentences/questions. My advice is to write my dinosaur routine (I will explain it later). Only after that, you can say - Ok, give me your number, so we can set exact time of the meeting.
2. She says - Depends for what

. Or - ???. Or something like that. This is the most common respond you will get, around 70%. In that case you write:
The second message:
We matched on Encounters (if you matched, if not just write without that first sentence), so I want to invite you to fly together with balloon

- She will laugh, or say something like - I'm afraid of heights or something like that.
Third Message:
Whatever she says you will answer cocky-funny, but don't go too far. Don't sound like freak. If she says that she is afraid of heights you will say:
Haha, ok, then I guess we can stay on earth in the beginning.
What you want to use as soon as possible is dinosaur routing. I invented this, but you can modify it if you want. Here is how it goes:
Ok, but I'm about to ask you one serious question. It can be said that this is elimination question, so be careful what you will respond. (No smileys, let it be serious) What is your favorite dinosaur?
She will say whatever, maybe she will tell you some dinosaur, or write like wtf, but for you it makes no difference. Whatever she says you say - Huh, that's a good answer, you did good!
Most of them will laugh and ask you why did you ask them. Here's a story, which is true btw:
I had one fucked up girl, who was all into dinosaurs. Her whole room was full of little dinosaur puppets, and she had like all the books in the world about them. But she was very pretty, so I didn't care about it much. Until one day, we had a fight, and she actually pissed on my car's bumper. So, I am traumatised since then and I have to check if you are some kind of Psycho that will piss on my bumper. I can't go through that again.
After that is easy... You will have nice chat, not too long and you will say again -
So, coffee, Monday or Wednesday 
Take her number and finish the deal.
3. Her third possible answer is something like - neither. In that case she has no interest. You can try, and say - Ok, do you have any other suggestion? If she asks why, you wil continue with balloon story. If not, fuck it and move on.
The point of this technique is high numbers. Send it to many girls and you will get a lot of answers -> dates -> getting laid
I had 24 dates and 14 FCloses in 40 days. With a little skill you can do better!
Let me know how it works for you... Cheers!
