This is true! I am forced to rely on hair pins and braids to keep it in check!
As an unrelated side-note that no doubt shall make some of you squirm in discomfort....one thing I really had to get used to here in Brazil wasn't the weather, it wasn't the language, it wasn't the food, it was the near constant penchant for Brazilian males to "adjust the contents of their packages"!
This is something that North Americans don't do anywhere nearly as much - I don't know if it's due to anatomical differences (many Gringos have had a habit of 'taking a little off the top' - permanently with a surgical scalpel - for decades), size differences (God has indeed blessed Brazil with an abundance of riches in many areas...
), the fact that Brazilians are in general less self-conscience with their bodies (as is exhibited at the beaches here)and open-minded (as exhibited by the pirated porn DVD's sold openly on every street corner or newsstand), or it has something to do with Latino machismo that also exists here, but the fact is Brazilian men constantly pull, tug, grope, pet, pat
and seem to lovingly massage
their gonads constantly
Americans may do an occasional 'tug' if their 'tighty whitey's' begin to creep up on them, but nothing like the constant game of pocket billiards most Brazilian men have going on all day long. It's rather distracting when you first arrive here.
Of course no one pays much attention other than the gay gringos who think they've died and done gone to Homosexual Heaven. It's not done purely for comfort, it seems to be done as a habit, often occurring upon the telling of a joke or the passing of a female, or out of general boredom while riding in a packed Metro car with their crotch inches away from the face of a seated passenger. There also seems to be a herd instinct involved...when one male in a group makes an 'adjustment', invariably others will also shift the contents of theirs in short order...perhaps in an attempt to keep the Earth in balance, I'm not sure.
Of course I've never paid any attention to this phenomena myself, only having heard comments made by others visiting here, and only pass on the information for purely scientific interest, needless to say...
