Hey there, welcome!
About your situation:
If you know all the girls already then you should kino with them, thats the first step, be cocky/funny and show them a side of you that they never knew about, be sexual, become wanted.
What I suggest though is that you go out, in other towns where you know nobody, or maybe a friend who can take you to bars he likes. Bring your own group of friends and socialize with the people there and use all the techniques that the arsenal of PUA books has to offer, or at least the ones that work for you.
If you cant talk to girls you're attracted to, you have approach anxiety, read this post by xfman overcoming-approach-anxiety-vt1672.html
Read a lot about this subject and actually DO the exercises they tell you to do
doing is the only real way to achieve, not just reading.Best of luck bro,
