There has to be a balance with these clubs and I do think that while well meaning if no one has done any safeguarding assessments they can go wrong.
I wrote years ago on MN about the massive distress going to one with her friend caused my autistic DD.
She ended up in a massive spiral of anxiety including self harming tics because she didn't feel any kind of attraction, she was just hitting puberty and some don't feel attraction until puberty hits. She kept repeating but I need to decide who I like as everyone is either gay or not.
The club was also mixed ages and discussions on the needs of the older group ( safe sex STDs) further increased her anxiety. Yes 11 year olds need to learn about these things but in a structured way hence PHSE.
It was also the emotional trauma that some were talking about in the group its fine for a supportive group but children are not counsellors and the emotional burden was high.
The club was also the only lunchtime club and one of the only warm dry places in winter except the canteen which couldn't fit all the kids in and was very noisy.
I raised with the school that this is poorly thought out and a safe guarding risk with the mixed ages, plus what training did the teacher have in pyscho sexual counselling to help someone like my daughter who was unsure.
We eventually moved her schools this was the final nail in the coffin for us they were supportive verbally but did nothing to support regards actual needs.
Within autistic parents I'm not the only with a story like this and it does immense harm luckily she never self harmed in a massive way but some do.
She's now a settled happy 16 year old, who once she'd gone through puberty discovered she likes boys. I wouldn't care either way along as she's happy.
A badly thought out club that doesn't look at these things through the different lenses of all the types of children in the school is basically doing some of the children more harm than good.
