DS has told me that a boy (who he dislikes) is very sexual with a girl in his class. He lies on top of her and 'does stuff' and he gropes her. I think the groping is over the top of clothes but is sexual as in he gropes her breasts and vagina. (she doesn't have breasts as such, she's quite a skinny kid)
Writing it down makes it seem much worse.
Ds says the girl screams but I definitely think its consensual. This happens at playtime and they sneak of without the teachers knowing. DS is adamant that the staff are unaware, but they would be in trouble if they got caught. He says nobody will tell because it's so embarrassing. DS really doesn't like the boy so likes to paint him in a negative light.
I remember people having boyfriends/girlfriends and doing a bit of snogging in year 6/7 but this seems to be basically dry humping.
So is this something the school should be made aware of, or is this normal 'kids experimenting' stuff that I should keep my beak out of? (DS is my eldest and quite a 'young' 11)
