Mumsnet user docomein said her partner was “right at the point of delivery” when their son walked in the room in the middle of the night and caught them.
“This morning he saw the neighbour and told her all about it, including a rendition of the funny noises mummy was making,” she wrote on Mumsnet on Sunday 20 November.
“He said: ‘Daddy was doing press ups on mummy’. We were a bit drunk, had just sent the babysitter home. I checked on him and he was sound asleep.
“How can I stop him telling everyone?”
Some parents on the Mumsnet thread had some serious and practical advice.
“I’d tell him that mummy and daddy were having private time and that he shouldn’t tell other people about it,” one person wrote.
Another advised: “You can easily say to him that you were having a special cuddle, or whatever you want to call it. Say mums and dads do it, which is lovely, but it’s a private thing and not for telling everyone about.”
But others just found it hilarious.
“Just be thankful you were in the missionary position and not doing doggy style,” one wrote. “That would have been far worse.”
While another commented: “I just burst out laughing at work. Just go with the flow, there’s not much you can do.”
Several mums decided to share their own stories of kids walking in the bedroom, to show the mum she wasn’t alone.
“If it helps you, my friend and her husband only realised her four-year-old had come into the room mid-shag when he suddenly yelled: ‘Faster daddy, faster’,” one person shared.
Another commented: “Our seven-year-old heard us having sex the other night, he was in his room but his door was open.
“He shouted to us: ‘Are you two bouncing on the bed? Can I play?’ eek!”
One mum also wrote: “Our eldest daughter came in on us once when she was eight and just stood there.
“When I opened my eyes and saw her, my husband said immediately: ‘I was having a bit of an asthma attack and mummy was helping me’. She said: ‘I thought you were having sex’ and walked out.”
