Welcome brother.

You just returned yesterday and you feel like this? The urge will grow stronger the longer you're away.

You're in the club now.
I do however disagree that Brazilian women are more conservative, I chalk that up as that experience being Salvador which is more 'traditional' Rio girls are sluttier than women in Vegas and Miami because its a vacation spot, and people from all over go to hook up. Basically, it matters on your city and communication. Sao Paulo was even easier, it was like NYC where, people spoke english (since its an intl city) and just being a foreigner gave them interest.
I could see places like Salvador, Santos, Curibita being more difficult tho, they're smaller cities and people are more conservative and religious.
Everything else you wrote however, was spot on.
I'm not too concerned with it being a sausagefest, I got friends there and they're some of the best brazilian wing men you can find, but if you're solo it can be a bit tough since groups of wolves can pick off you and cock block real easy, its just easier to go with locals who speak the language, know how to talk to brazilian women, and are winging for you with all your interests in mind.
