yea i've head this kind of trend is quite common in pak...mostly among the elite. it seems that girls here in the west are becoming more conservative and the girls in the east are becoming more "westernized".
When my 16 yr old neice went to pak for the first time (she was born and raised here in the US) kids her age couldnt believe she never went clubbing, nvr drank, nvr smoked, nvr exposed her body...and they were totally shocked to hear she didnt have a bf! They told her "all the kids here do it".
U missed out "never watched porn movie" in that list. Trust me, they all do that too, and still can't believe us westerners are not appreciative of such films.
