I'm going out for a friends birthday tonight, we're getting dinner and then heading to bars in the city. I'm 6'3", 220 well built good looking guy. And I can approach women and speak to them no problem.

For reasons I don't want to get into, I have a hard time reading body language that is inviting me to move further. For example, I was a bar dancing and a lady looked at me, smiled, and booty bumped my way - but I kind of froze up. I'm generally worried of coming on too strong and offending her or giving anyone the impression that I am harassing the person.

So the advice I'm looking for is: when I'm speaking to someone or get body/verbal cues to move forward, what is a good first step to build intimacy in a bar/dancing scene? Sounds dumb and obvious -> dance with her. But I'm just looking for whatever people have to say before I go out tonight.
