about the hugging and genital grabbing described, well uhmmm... we, the peruvians, are a little bit chauvinism (sorry, but I do not know the right word, in Spanish is "machista") so if you do that here (except that you are really really drunk) you will be considered as a gay ("cabro" in slang)
I really respect all the cultures so much, and for that reason is that I was asking all these questions for not being considered rude or disrespectful to Finland people, by the way I had the opportunity to travel there for a week at most and I really like it too much, it was really peaceful and beautiful
I suppose that one of the biggest obstacle when one visit a foreign country is how to interact with the opposite sex (in my case girls), I remember that once when I was in Joburg I felt a little bit homesick and wanted to distract my mind going to the movies or going to eat something with some girl (only that and not to have a date), but I messed all it up: first I invited a Indian girl, she told me that she could not go out with me, because it was not allowed; when I tried to invite a white girl she thought that it was really a date, and when I invited a black girl she was more cool, but the problem is that after I invited her, she told almost half of my classroom that I wanted to be with her
at the end I finished buying a bottle of wine and drink it with a few good cigars alone, geez!
