Hey welcome to the community,
I definitely know what you mean with the girls are less open, I come from Holland where partying and social life it completely different from what I think it is like in the US or England, people here are only open when they want to meet people, which means most of the time you will get ignored if you don't display higher value. But while they might be harder to open I have found that the rules are still the same negs, DHV, and the like all work the same.
Once again welcome and good luck
