Porn is obviously not something that should be used as sex ed. Having said that, sadly, porn is the only sex ed provided to our countrymen.
It is true that porn is exaggerated and should never be used as a benchmark. The people who star in these movies are paid for it and have all the time and money to invest in their career and to look as beautiful, busty, big and shaved.
But picking out positions/techniques from porn is not bad. Until we have proper sex education classes in Pakistan, I say Abdullah Tariq is right about this piece of advice.
