I'm currently doing Neil Strauss' (Style) "The challenge" (it's a book with lots of excersizes to become more socially adept and get into the game) and I'd recommend it to anybody new to pickup. I'm not that new, it's just that I got a girl friend shortly after getting introduced to pick-up, so I kinda lost my motivation and things have been sliding the last few months... so when we broke up I thought I might as well start from scratch"
Anyways, my situation is pretty similar to yours.. most girls seem to find me attractive. Maybe not head turningly (is that a word? ) so, but at least in a "hey, that guy is kinda cute" kind of way. And I've also had some girls (at least 2-3 different sexual partners a year), but most of them came to me, not the other way around My ex girl friend really was my first pick-up (where I had any kind of game going whatsoever) Anyways, I think this book is great for getting started, tightening your approaches and building confidence. I already know quite a lot of theory, but "The challenge" is all for practicality, which suits my way of learning 
I hope this doesn't come off as a shameless endorsement... but I really dig this book and think it would work wonders for you too
