Hey Fakhry, a couple of points:
First of all the "Later Loser" might have been a little harsh especially with the neg, but if it was an established thing, then it was probably fine.
Now the more important thing. You made the mistake of going after the girl the way she is used to, and the way she wants it. Like Stripper game, you want to downplay her sexuality at first. That will intrigue her, and make her more interested in you. A lot of women will act really slutty, but they won't actually do the dirty with you. They love to flirt. It's a power thing and it is also a defense from getting intimate.
Something I have done in the past, and most people have done it at sometime, is to show some sort of vulnerability when I felt insecure. The thing was that the vulnerability I showed would be something I didn't give a f*ck about. That way I could redirect criticism to something that didn't really bother me. This isn't necessarily a good thing, but it is a natural reaction. Some women do the same thing. They may be frightened about intimacy so they will say they are really slutty because it makes men act in a predictable fashion. Something that they can control.
The neg was good, above. Next time you get a chance to talk about her, steer clear of sexual topics, and ignore her attempts to flirt. Otherwise build attraction like usual. Just be extremely careful to never reward her when she initiates intimacy. If you do it right, you will build sexual Tension, and make her come on to you really hard because you aren't reacting to her advances. Note: it is very important that you understand that you are still building attraction, but you are being extra careful not to respond when she initiates. Also hold out a little longer before you start seriously sexually escalating. When you finally start sexually escalating, you will want, and be able to sexually escalate much faster than normal. Finally, don't be surprised if right at the end, she puts up some last minute objections. She likely has some hang-ups and you are going to have to be able to gently work around those.
