I very rarely post or come here, but I thought I would throw in some info.
I am fairly quiet and I have hundreds of friends and I get laid every few days by someone and I havent had a GF since August of last year.
I am 6'3" and ~215lb and look pretty good.
The trick to being a "quiet natural" is realising that most of your comunication is non verbal.
You have to be "non-threatening" which is basically having a desperation factor of zero.
You have to know people where you are doing the pick up, security, bartenders, door guys, DJ, waitresses, and customers. What this tells the girl is that if all these people think you are a cool guy, then you must be. Don't brag about it either, just let her watch you talk to them - they are your friends after all.
I talk *very* little to the girl I am interested in, no more than 5 minutes at a time. I then go to a group of friends I know, and another group, and another, until I have made my rounds of the bar and get back to them, and dont parade her around the bar to all your friends, she is a f*ck... that is all. My friends dont even know who I am f*cking or if I am even friends with someone I am talking to.
I am extremely comfortable around girls and don't mind touching them, especially their hair or ill poke one boob or sorta motorboat their cleavage with my finger. Girls that don't know you will sh*t test you after you do it nearly 100% of the time, you can just tell them its a compliment and if they dont like it then they shouldnt have such good looking ____ and then give em a hug to make it all better. In the case of poking one of their boobs, my favorite is apologizing for accidentally making the other boob jealous, the bigger deal you make of it the better... extra points for asking them if you can even it out. I recently poked a girls boob as a opener cuz she had huge boobs, then made a big show of looking away so she would know it was me, ive been f*cking her once or twice a week since January, I had never talked to her and knew none of the girls she was with. Girls like to be touched, they just don't like to be grabbed or molested, notice that I only use one finger when I touch their boobs.
If a girl seems concerned about it, I go to lengths to make sure a girl knows that I wont kiss and tell, and I dont because when you are getting laid a few times a week it isnt a big deal. Girls are real big on not being thought of as a wh*re, but they like to get laid as much as any guy.
Do not ever lie to a girl about anything, it will always blow up in your face.
Don't ask for permission, the answer is yes unless otherwise noted. Even then you call call em out for living like its 1950.
Never grab a girl, ever.
Never touch a girls ass unless you are spanking it, and only if she asks you to.
Do not touch a girls waist, it makes them self concious.
Dont touch a girls boobs if they are anything like small, see above reason.
Dont be afraid to introduce yourself to her friends.
Dont hug up on her, space is good.
If she brings it up, tell her from the start that you are not dating, you are just having fun.
Oh a nearly forgot the most important thing, smile and have a good smile, and white straight teeth, you can get laid for that alone. No girl wants to kiss jaws. Smiling people are fun positive people.
I also make a point of remembering who I have talked to and if I see them out again ill walk up and say hi. I always try to be very friendly with everyone, even girls I have no interest in.
Remember that the less you say, the less likely you are to say something to mess it up.
