I had a quick look a the Finnish version from the Internet and I did not understand much, but it seemed to be similar to other versions of the show. I did not make the connection between the advertisement and the state of the candidate, but it could be that there is one... I guess if you have your cock on display on TV you may want to shave it, so that it appears bigger, rather than lost in a forest of hair. But trimming is good for that too.
Anyway, it's funny how some countries have no problem showing everything, while some (France) blurr genitals (but not butts and breasts), that says something about how unequal and sometimes how weird various standards are. I guess it was the same with the mother of all reality TV shows "Big Brother" and its various national variations.
