I think it's actually the opposite. If you get into kino early on, you can more easily open the door for emotional intimacy. If you become emotionally intimate early on, you won't necessarily have the green light for kino/sex.
I say that from experience. I never had any issues becoming close friends with girls. I could get them to open up to me about their secrets and their insecurities etc. and I could share mine. But I couldn't bang any of them!
A girl will share her insecurities, secrets etc. with her friends. She'll discuss these things with gay guys. In fact, if she is discussing these things with you and you're not in a relationship, there's a good chance she's not sexually attracted to you. When you don't know a girl well, she should be trying to impress you and present her best image to you if she's attracted.
So don't wait for the kino. Start working on kino IMMEDIATELY. Just start out with some light touching after jokes etc. Then just start touching her shoulder. Then you can progress to putting your arm around her. Then you can move it down to the most curved part of her back.
If you have kino going you can be talking about the most superficial topics and STILL get laid. Like they say over and over again on this site, it's not what you say, it's HOW you say it!
The green light for sex isn't in what she says. It's what she allows you to do. If she's allowing you to touch her in ways that she wouldn't allow most people to touch her, she's ready to get it on.
