Graphic sex scenes in ex Yugoslavian movies

Graphic sex scenes in WR didn't shock me much because there were many Yu movies on TV in the 80s with random and obligatory sex scenes. I get used to it early on. Those scenes didn't show genitalia, but they were shown more as a disgusting rape scenes and unnecessary torturing of women, gnawing their tits in almost every damn movie from mid 70s and 80s.

What did shock me is male genitalia - something that was never shown in Yugoslav movies - 1 out 10 showed it. This one shows full errection, that was a surprise. With first Yu porn flick appearing in late 80s, this was a pioneer film in hard core sex, this is the only thing that is interesting in it.
