I have noticed this over the last few years. I don't mean the silly "oooh do you fancy Miss" nonsense that dates back to my own school days, but boys who are often only twelve or thirteen, using the most disgusting sexual language and threatening behaviour towards the female staff.
In my last school, we had a boy tell a female teacher he'd "shut her up with his dick", one member of staff who was pregnant went on maternity leave early, because she couldn't stand the way one boy was behaving around her - comments about her bump, staring at it, talking about how everyone knew she'd had sex.
This was on top of the daily comments on appearance, claims that they can smell fish in female teacher's classrooms. Not to mention the amount of English essays which were basically porn.
I've just found out that a new boy is arriving at my current school - he was asked to leave his last one for sexually harassing female pupils and staff members. Now he's just being shifted sideways to another school, with no additional support put in place.
I have also noticed that the way many of the boys speak to the girls in their classes has changed too - lots of sexual talk, anal sex is frequently mentioned, disparaging comments about public hair. They don't seem to care if adults can hear
I don't seem to remember this from my own school days. We weren't angels by any stretch of the imagination, but we simply wouldn't have sat in class talking about anal sex, and the idea of a boy sexually harassing a female teacher would have just never occurred to us, it simply would not have happened.
I don't know if I'm just getting old and looking at things with rose tinted glasses, but there seems to have been a distinct change in boy's attitudes
