Yeah I see what you mean so here you go. But as much as I would like to put my name to this theory I can't. It's not my own work, but only what I can remember from a book a read once. They called it ''the 12 Steps of Intimacy'' but really this is the Kino ladder as good as you'll ever find it.
1. Eye to body. The old once-over, except it happens in a fraction of an instant. Only a few significant details are absorbed. And attraction is decided upon within the initial moments. A few seconds at most.
2. Eye to eye. Eye contact is sustained. If you stare, it's considered rude or an act of aggression.
3. Voice to voice. Ranges from small talk to intimate.
4. Hand to hand. This requires some trust. Hand to arm counts here, too. General kino can be applied here as an excuse to by guiding the girl where you want her to go (through a doorway).
5. Arm to shoulder. A hug or embracement.
6. Arm to waist. Can be sexual, especially if "waist" is considered the small of the back. You wouldn't do this to another man.
7. Mouth to mouth. Full frontal contact during a kiss.
8. Hand to head. Requires trust. To possibly encase a girl's head whilst kissing.
9. Hand to body. Any part of her you want. Breast, shoulder, chest. Its all available.
You will probably have noticed that all these acts could have all been ''performed'' in public. But now things heat up. Hopefully you know what the rest means..
10. Mouth to breast.
11. Hand to genitals.
12. Genitals to genitals.
Again: This is not my own theory, just what I have read.
