The post, which was written on Mumsnet, has left many users shocked after her son was given a lesson in ''sex'' education by his friend's 15-year-old brother who schooled the child about sexual intercourse and ''condoms''.

Writing in the post the outraged mum wrote: ''I was slightly disappointed that we hadn't got in there first with 'the talk', but happy he had come to me to talk about it, so we went over everything.

''At one point he asks me if sex makes a baby every time. I said no you can use contraception, he said like condoms?''

She then writes about how her son found out about the ''talk'': ''Apparently what happened was at his friend's sleepover his 15-year-old brother had come into the room and told them about sex and condoms. So we talked about the age of consent and emotional maturity and things.''

''Right at the end I mentioned porn, and just said that he'd probably hear people mention it, but that it was a very false type of sex, and in some cases it can be very addictive and impact upon relationships.

''Son goes all quiet and then says actually his friend's big brother told them to Google porn, so they did. They watched it (about six of his classmates) and then they all thought it was a bit wrong so they turned it off.

''Feel really down this has happened. We have parental controls on all the devices in our house and keep an eye on what the kids are looking at.''

The mum admitted she was disappointed and added: ''I expected this to happen when we hit teenage years, or even high school, but he is NINE, he has still got 18 months of primary school left.''

One shocked user replied: ''I would have to speak to the parents tbh. It's one thing telling them about sex but getting them to Google porn? Such a shame.'' (sic)

Another added: ''I would go to town on it. It's so inappropriate.''
