How to sexualize with a language barrier (Colombian girl)

I recently met this girl who moved here a few months ago from Colombia. Her English is poor, but we can communicate decently well (using google translate sometimes). I have two questions: (1) How do you sexually escalate when there's a language barrier like this? I found that a joke or comment of any type was lost in translation. It was very difficult to be flirty. (2) How much should you (or how do you) sexualize with a Colombian girl in particular? I've heard that sleeping around is more stigmatized in Colombia. In addition, she doesn't like to drink. She's a good quality girl so I wouldn't mind waiting to escalate things, but I have no idea how to go about it.
