Slightly before the "frizzling" Frenchmen started their famous Emmanuelle-series, the tardy Dutch had Turkish Delight already available and attracted millions of viewers... Well, they are not directly comparable, but movements and changes in views that began to form in the 1960ies enable to realise such creations for "ordinary" people as well. The film in question is pleasantly moody, showing various angles of love-sex-relationship, and courageous character actors (particularly Monique van de Ven as Olga Stapels, Rutger Hauer as Eric Vonk), skillful directing (Paul Verhoeven) and cinematography (Jan de Bont) provide this not-so-extraordinary script additional values and undertones.
At the same time, I have doubts that Turkish Delight is a timeless film, that it approaches and influences future and current people as well, as many attitudes have changed, and many would consider depicted fashion and hairiness as odd (mildly speaking). And those accustomed to Internet have seen much "bolder" stuff...
