I'm going to go to South America for six months next year. How can I impress the women there?

I'm a 27 year old American male in pretty good shape from triathlons and futbol, and I'm working on my spanish. I hope to be at least pretty proficient by the time I go. What else can I do besides look my best and know the language to impress, let's say, a Peruvian princess? I'm a musician, so that works well here, but I don't know how many pianos I'll find that I'm allowed to play in Lima. I know there's lots of to be had in SA, but I won't pay for it. I'm much more interested in making REAL women genuinely like me. They say it's the land of "machismo", but would a different approach work better for a foreigner? If it matters, I'm going to Colombia, Ecuador, Peru, Bolivia, Chile, Argentina, y Brasil.
