remember teen boys can go to R rated movies and see older guy's Playboys so they know what a women looks like. In this case(many years ago) there was no porn and the first time a girl saw a penis was when it was in their hand. That is why kind of pure, demure girls gave handjobs (blowjobs not that big until late 80s), to see a real cock and balls. No one wants to be left out
