If she's wearing a chunky ring you can examine it, tell her it looks like a knuckle duster and role play that you're going to hire her as your bodyguard (not such a good idea if it's an engagement ring).As you continue with the interaction aim to make your touches longer, more obvious and more sexual (there's more on escalating your physical contact from friendly and social to sexual in the Triad Model).Get some physical contact in at high points during the conversation.If you are about to say something funny then it's a good time to lightly touch her elbow.In some countries, such as Britain, this isn't an automatic greeting and can be awkward if it isn't done confidently.Hold your arms wide open and make it obvious she's getting hugged...It's important to keep aware of her reactions when you touch her.If she's uncomfortable you should stop, wait, then try again later. Until you've kissed her, she still has plausible deniability.
Every time you make an advance take a step back and pause before you go ahead again. By taking two steps forward and one step back you remain a challenge and keep building the sexual tension.By making physical contact while saying something interesting it makes the touch less conspicuous. Don't be afraid to give her a playful shove if she says something geeky or tries to tease you.Taking a close look at her jewellery, tattoos or anything similar can be a good excuse to get some touching in.Touching provides you with the steps to get from one to the other.It builds up sexual tension and keeps you away from the "let's just be friends" zone.
