Hej guys in my country girls are more different, they doesn't get on date with you without knowing you first, so you have to text with her for one period of time than she will go out with you and I'm fun and I have a great life but I don't have so much time to invest in one girl and I don't have a clue how to build connection in that stage, when to go for sexting, where to be relatable and so on, so if you know any method, book or something that can help me I will be appreciated.

Edit: I'm great in openers but along the conversation the fun dies out and gets boring.
