boyfriend girlfriend.... prostitution (that's pretty fucking big here... if you go to bahrain on the weekends, where prostitution is "legal", you'd find around 500-800 cars with saudi plates parked outside every hotel to get laid or drunk)... things like that...
and about that last point... A LOT of middleeastern people don't understand english (i'd say most of them), so even if they see what's going on tv in other countries, they still wouldn't understand what the fuck it is due to language barriers... and i don't know about other countries, but around here we take "religion classes" at school (about 30% of all hours at school) and in those classes they teach (brainswash) us about "western" culture... and the general consesus is that western women are basically all whores who act like animals and want to "commit adultry" just by seeing a man... and we are basically taught that any woman who doesn't cover up her face, especially if she puts make up on, is a whore and wants to get raped.
so, yeah... that's probably why...
