The curved dick (which is what I think you were asking about when you said the dicks are kinda strange) is caused by either 1 of these two things:
1). Tucking their cocks (hiding the penis to an angle inside a tiny pair of panties)
2). A curved penis condition which is naturally caused (sorry- I am unaware of the true medical term).
Brazilian plastic surgery isn't any more advanced as other countries- it's simply cheaper and more accessible. Laws are different and buisness is booming.
