Flckety that's an almost identical description of the conversation i have just had with my friend over lunch. We remember youths and men descending on us, hands ready to grope, ams round our shoulders before we even knew their names, and rebuffs being met with 'you must be a lesbian, frigid, you know what you need (nudge, nudge), oh! do you only put out for money?' and on and boringly on!
Office pests would pinch bottoms, and we would be blamed if men wolf-whistled. Complaints were futile, and new, young office girls would be warned 'watch out for so-and-so, he's a perv.'
No wonder feminism took off in the 60s. The sexual freedom of the pill and pop culture gave free rein to men thinking they'd hit the jackpot. Many girls with more freedom were not protected from the likes of JS exploiting them.
I remember going on holiday to Italy at the age of 19, with three girlfriends. The Italian youths would shout obscenities at British girls, and make sexual gestures. The middle-aged managers of our hotel and the one next door would escort us up the road to our destination, explaining 'the trouble with these males is that they don't understand that helping yourself without permission is theft.'
Under-age groupies should not have been exploited, but given guidance about their behaviour. However, no man is going to abuse a girl if the opportunity arises unless he has the motivation, sexual interest in that age group, tells himself it's ok to do it, and can separate her from people who will protect her. That takes a deal of planning.
