Hi!
Here is my story. I am not a PUA expert, I am not familiar with most of the techniques that you guys discuss, however I consider myself quite effective because the way I behave instinctively seems to be the proper one and when I decided to go through some o the PUA websites I discovered that I was doing some things in a natural way. However I have several issues that I would love you guys to help me with.

I may suck at picking up girls in clubs (I don't feel comfortable o  such places), however I am quite good at doing this in places that all not widely considered a "picking up places" (of course you will say different, but I mean that most people rather do it in clubs than for example in a bus). 

Whether it is cafe, street, university, elevator, library, shop or any other place I feel that I have quite a strong start, mainly because of two reasons:
- The girl knows that lot of guys looks at her there, but I am the only one who actually does something about it and starts conversation
- my opening line is usually not something generic but situation-specific (I spot some detail about her or situation and use it as an excuse to start conversation)

When the conversation starts my greatest asset is ability to talk fluently on various topics (really, she could pick almost anything and I could easily find myself comfortable in it) and I have really good improvisation skills (one thing that I don't handle that well is when the girl is unfriendly bitch from the start, but that's not that big issue for me).

I think that most of the times I am able to get one of those things:
- phone number
- Facebook details
- instantly set up a meeting (eg. If you will be here in a few days at the same time we should meet. / Fine, I will be there.

Note: those situations are not forced. It's not that the girl gives me number because of pressure. To test this I give them my number without asking for their and they are the ones who text me later, although they could easily not do this. So defnitely there is initial spark and my first meetings are usually well played.

Where is the problem then? It appaears when it comes to follow up. One of those things may happen:
- everything can go according to the plan (No need to write more, because there is no problem in that)
- girl friendzones me for unknown reason (maybe I develop the situation too slowly?)
- she starts to consider me as a serial pick up guy who approaches plenty of girls (is that because I did so well at the start?)
- she loses interest (is my text game lame?)
- And most important issue: she wants to have sex and also seems to want to start a relationship with me (which is not something I am looking for)
