I plan on writing a book about Latin American dating based on actual experiences. Any recommendations?

The plan is as follows: I currently have a good chunk of money saved up, and I keep saving. In January of 2009, I will start a trip through Latin America, visiting every single country in Central and South America. The plan is to spend a year on this trip, and along the way write my experiences involving the women I meet in my journey. I will then, upon my return to the US, write a book based on my Latin American dating experiences, in order to help American men who may want to meet, date, and possibly marry women from Latin America. I am a 23-year-old white American male, never married, who speaks Spanish fluently, having travelled to Mexico a lot and dated several Mexican girls. I honestly feel that if I’m not careful, I may end up married during this trip; apparently in some parts of Latin America white America males who speak Spanish get sexually harrassed by hot Latina girls. Any recommendations for my trip and/or book? (And yes, I ask this in all seriousness).
One comment: yes, I already know that in Brazil they speak Portuguese. I have devoted myself to trying to learn that language too.
Thanks for the consejos, the truth is that I never andar como un gringo rico (wander around like a rich American for those who don’t know Spanish). I don’t wear any jewelry at all, not even a watch. I wear plain clothes that make me look like an everyday Joe (which happens to be my name!) In fact, most people don’t know I’m not Mexican until I begin speaking Spanish (I still have a slight American accent when I speak Spanish). In other words, even though in Mexico they don’t use the term "prepaga" (they prefer the term "interesada"), I understand the concept perfectly as I have met several women of that nature, and have learned how to avoid being ensnared by them. However, I also know that not all women are like that either.

Make sure you have your return ticket ready. You will come home penniless. Hide your wallet. Pretend youre poor. There is the concept of the prepaga in all South American countries. IE You get what you want if you get her what she wants. Hide your wallet, pretend youre poor and find true love. If you dont and you flash your cash and your clothes you WONT find love. You WILL get laid, but only till the money runs out. Also, if you flash too much of anything, you might get robbed or worse. Be careful. Write your book. start at www.colombiancupid.com
