I think this thread has now taken a very interesting turn, and has provoked much thought in my (rather old) head. We seem to be considering the different mindsets of young girls and young teens regarding having sex, from the sixties/seventies compared to the present day.
There does seem to be one constant, which is adulation of 'stars' and desire for contact with 'celebrities' and the media. There appears to be a tendency for lassies to follow wealthy and famous men around (eg footballers, singers etc) and to be prepared to have sex with them in an effort to participate in their hedonistic lives.
There are two points (IMO) to consider. One is, how do we feel about legally underage yet physically mature young girls doing this, albeit voluntarily? And is it actually abuse on the part of the (usually older) men who enthusiastically take up their offers? The married teacher for example who took his young pupil to France was pursued relentlessly and arrested for it. Yet quite young girls drink and have sex all over the place (in local parks for instance) and no-one appears to do anything about it. What constitutes abuse?
