as mentioned previously the op said she posted in the wrong board, possibly because she was guarenteed immediate response.
Due to the board name AIBU..i'm sure she struggled to think of a way to phrase the title properly and just wrote the first thing to enter her head...that is my assumption..innocent until proven guilty.
We all agree the title is unpleasent and the majority of people either wouldn't have sex or would stop if a child came into the room.
Perhapse dc was playing in the room and looked through now and again at mum and dad in bed chatting and they thought in, between dc visits...in a silly giggley way..lets have a 2 min romp about. I didn't get the impression it was candles, massage and mills and boon style passions aflame stuff. Like I said, Is it possible that they just got carried away for a moment, looked up and there was dc sitting on the bed? I know my dc can sneak up on me like little ninjas.
THIS IS NOT A HANGING OFFENCE!
she may have asked at what age it is innappropriate to have sex with dc in the room as a straight forward follow on from "oops, this happened, will dc be ok, have other people done this...when did you stop...IYSWIM.
There is a load of jumping to conclusions, judgement and "string em up" going on.
As a new poster, I am finding it a mixture of horror and LMAO.
