Don't worry about the conservatives on sites like this. It's nothing new - years ago there was this character called Mary Whitehouse who was exactly the same - look her up, she's hilarious. So, every generation has to deal with prudish conservatives running around with their hair on fire because someone told a teenager how to have sex safely. Funny thing is how they get so exercised about binding being dangerous and then completely explode if someone mentions how to do it safely. Ignore them, and even more importantly, never become them
So you're more than happy for 11 year old girls to be directed to sites that promote dangerous sexual practices, when they are far to young to even be considering having sex full stop. And don’t even think about replying that 11 year old girls are having sex left right and centre, because thats not true. An 11 year old girl may be very petite - some at my school are around 4’ 6’ and around a size 4. If a male (or indeed another female) attempted to ‘fist’ them it would cause told damage. But you're OK with them being exposed to such a dangerous practice? You think it’s only ‘conservative’ women of a certain age that think this is wrong?
That speaks volumes about you - and not in a good way.
