• Parents shared how they found out their offspring were sexually active
• They range from honest and open chats to highly embarrassing situations 
• One daughter accidentally sent dad a saucy message meant for boyfriend
• While others were shopped after mums and dads found condom stashes

Meanwhile, gemiddie's son opened up to him about his first time voluntarily - but went a cringe-worthy step further by asking if sex will improve with time.

'Went camping for the weekend, leaving my son (17 at the time) at home alone. When we returned, he waited until his mom was inside the house and said: "Dad. I had sex this weekend." 

'I took a deep breath and asked: "Did you use protection?" He answered yes, and we talked a bit about the circumstances. After all was talked about, he asked, "Dad. One more question. Will it last longer?"...I tried to not laugh.'

Meanwhile, it was BodhisattvaJones's son's spurned lover that revealed his news. 

They said: 'When my son's recently dumped girlfriend started texting my wife claiming she was pregnant. I pulled him aside and he admitted to having sex with her but outlined why pregnancy was very unlikely. Not really details I enjoyed hearing but ones I needed to hear given the circumstances.'

And user wereusincodenames found out when their son was caught in the act with his girlfriend and he had to call home as he 'thought the dad was going to kill him.' 

He said: 'I just laughed and told him a couple of stories from my life and the time when his uncle got caught doing the same thing.'

Others found out their children were sexually active when they discovered condoms, like Redditor svlvaing, who found one used in the trashcan as it was being emptied.

'And in the other room, my brother burst out laughing and said: "Not likely". Me and my dad just looked at each other and that's how he found out I wasn't a virgin.'

And for Deroule, it was his big mouth that gave him away. 'I was bragging about it to my mates whilst playing the Xbox 360 back in high school. 

'My room was right next to the kitchen (just where she was at the time) and she overheard. Next day she bought me a pack of condoms as her way of letting me know she knew.'

But LoverOfDeath's was among those to top the list of horror stories, as it wasn't just their mum who found out - but her entire family, including grandparents.

They said: 'My mum found out that I lost my virginity because of screenshots. 

'I was telling someone about it and their account got hacked (my mum believes it was a fake, I'm going more towards fake) and everything I said was screenshotted and sent to my ENTIRE family, including my grandparents (who I have had no contact with for four years, this came out two and a half years ago).'
