ive been seeing this girl for like 2 weeks and i have been picking her up and we'd chill at my houses say once every three days but my problem is that im not getting anywhere like we kiss say 3 times when she's around but i always have to lean in and she doesnt really touch me in a sexual way like we tickle each other messing or whatever but it doesnt really lead anywhere? what should i do?

What do you mean by "we kiss"? Like a peck on the lips?

Is she very shy?

If so, you must lead more. Go cavemen on her if need be. Pull her by hair and kiss her passionately.
Or simply state your intent, that's what I usually do when I have strong IOIs from a girl. Tell her you like her and then go for the kiss/make out.

we kiss sometime we tongues like when i drop her home.. but like when we be at my house its just pecks and that

I think I really don't get it. You can make out with her, but can't go any further? Just grab her and start passionatelly kissing her at your place. Then escalate sexually (brests etc), what will she do? Just sit there with her arms by her sides, like a figurine?
She will either stop you or play along. If she stops you, then it's probably best to somehow find out what is wrong. Or perhaps better just lean back for a while and try again later.

If she is shy, she might be very nervous. You must lead the seduction all the way to sex on your own without her help.

but the thing is how can i escalate to breasts etc if she pulls out after like 2 seconds of kissing i'd look like a freak just randomly touching her breasts after 2 seconds

Oh, I see. Well that's weird really. How do you usually go for the kiss? Like "romantic" kiss, or more of a playful kind of way?

I usually make the girl laugh, tease her and then go for kiss when she is "high". Then I usually lie on her and make out. She can't easily get from under me, can she?
I'm being dominant and she usually struggles a bit (a token resistance really) and then it goes quickly to arousal.

But this depends on your personality type. If you are too serious, then it's hard to switch to fun/playful vibe all of a sudden.

How about to get her (and yourself) drunk a bit? I don't like it that way, but if she will feel more loosened, why not..

well we mess alot like tickling and pinching etc.. but then it is hard to switch to kissing and then to arousal.. like so i dont know know i suppose laying on her kinda focuses her on me

Did you try to kiss her on her neck instead? Or bite? You could even try some fun roleplay. You know like most girls like the Twilight saga? So pretend you are the Vampire guy Edward and she's the Bella chick. Have fun with that. Smell her neck seductively, kiss her, gently bite her. Many women can be aroused by neck kissing. Play with her hair, even pull her hair.
Keep kissing her neck, and keep moving your hands around her body. Hair, back, arms, breasts, ass. Don't keep your hands there for a long time though. Keep em moving all the time.
Then try to go for the make out. If still not, just go hard core for the arousal and sex. Even without kissing. She might have some issues about kissing, it's hard to say..

Again, don't be afraid to lead. You are the man, you have to lead the way.
