I'm cross-posting this from my lay report from this weekend lr-joining-the-playhouse-club-vt71879.html :

Being new to the community, I don't know if this is all old news, but this is something that I use pretty often, and it works great for me. I've developed it myself, but maybe I've just been reinventing the wheel.

So, we're slowly walking down a road side by side. I lag behind a few steps to bring the pace down a tad more and to make her more aware of my position relative to hers. It makes her more conscious about me. Then I pace up slightly, just so that I'm walking one step ahead of her, and half-turned against her, I cut slightly through her path. It forces her to a semi- halt, and quite often, she will stop and turn to face you. Then you face her completely and go in for the kiss.

If she does not respond this way, this routine does not have any plan to convert her into a kiss, but it serves as a test which is pretty safe - if she's ready, you kiss her. If she's not, you just cut through her path. No biggie.
