Greetings! I know what you're talking about. I used to have this problem that I could just not make girls attracted to me, some were attracted and I could handle those ones from there easily, but most of them just didn't see me as a MAN.
You have to be sexual. Playfully of course, but you need to learn this. When you're talking with girls you have to make comments that are funny and sexual. Don't be afraid of this... It takes some time to calibrate this but once you're there it is GOLD.
Later on, it will be totally subconcious. I remember when on the campus me, a friend of mine, and a girl he knew(I didn't) were talking. Somehow the topic became that her ex was caring more about his video games than her.
Suddenly, without even thinking about it, I smiled and asked :"Was he fucking well at least?" Just a little moment of silence and then she said:"Well...that's the only thing he did well for 2 years" Then we all laughed. Saying something like this used to be unimaginable for me... I would have just said like "What a douche" or something like this.
Yes I was a little rude...Did I care? No. Have I seen signs of attraction from this girl later? Yes...Altough I wasn't really interested, that's another story. Be hell-bent! Of course, you'll also have to learn when it's enough. Girls don't like the all cocky arrogant douche either(but to tell the truth, they still get laid more than the "not-cocky-at all" type)
Good Luck!
EDIT: I've just read your last comment about kino. That's another thing that needs to be practised and calibrated. Touching shoulders and knees is a good start. For easy kino escalation I suggest you "The Claw". It is just fucking MONEY. You'll feel like a rockstar in that position and she will feel like The Bitch of the rockstar.
It is so easy and so natural. You just put your hands around her neck. You tell her something, and then you could even let go. Repeat it a few times throughout the night and hold on to it a little longer every time. Also, this clawing position is easy to turn into a kiss-close. You can also "Claw" her hips. All women shall bow before the power of The Claw.
