I know the thread is in the Sex forum and there is a lot of explicit stuff on there and there generally isn't much in the way of taboo things.
But a poster telling the OP that she should chill out because her 14 year old having sex with a 13 year old is " normal" to my mind is not the sort of agenda MN should be allowing.
Allowing someone who is normalising child sexual activity in the days of grooming gangs, child explotation and abuse seems a pretty irresponsible line to take.
