Im flirting with lots of girls for a while, some I met online, on street, or at school. But couldn't get laid still.

I don't get it, there was a girl at a class, she is 22, has a great body, perfect and likes to show it, wears the shortest skirts, lots of piercings, talks dirty but I couldn't get it on with her. She is totally interested, she is into me but when I tried to make it a bit sexual she got away. I seriously don't get it! If she wasn't interested then it would be okay but she certainly was, you can't escalate if the girl is not into it.

Most girls I meet wants relationships, like 95 percent? What am I doing wrong?? They hold of as soon as it gets sexual. Another girl 20, cute, a bit crazy but it's obvious that she had numerous partners before, we talk, it's all great, she is so interested that even if I text after a month she answers right away. Do everything not to lose me but when I make it sexual, again she holds off. What the hell?
