What we do in the privacy of the toilet is not something that often gets spoken about - and usually for good reason.
But one woman has been left traumatised after discovering her boyfriend's pooping habit, which has left her wanting answers.
The horrified girlfriend went on Reddit to question whether her partner's antics while sat on the toilet were normal - but was left stunned by the responses.
She asked: "My boyfriend just took his shirt off to take a shit. I've never heard of this. Is this a thing?"
The woman was flooded with replies - mostly coming from men who confessed they do exactly the same - and sometimes go even further.
The general consensus was that taking your top off helps when you're struggling on the loo - and some people actually go completely naked.
"Yeah if you know it’s gonna be a doozy, gotta strip down for minimal obstacles," wrote on person in the comments section.
Another added: "If it gets too bad, I have to remove everything, even my watch. Never had to remove my ring though, but I fear for this day."
"Sometimes you know it's going to get serious. You have to be ready. You have to be fully unencumbered. Shoes off. Shirt off. Sparring partner at the ready. Housekeeping on standby. Of course this is real. It doesn't get more real than this," said a third.
A lot of people were in agreement that there are various 'stages' - with taking your shirt off being the first of many.
One person gave a very clear explanation of what the different levels are, which coincide with how much trouble you're having releasing your bowels.
"Class 1: Fully clothed
"Class 2: Lifting shirt, hunched
"Class 3: Shirt off
"Class 4: Fully naked, leaning against wall, praying
"Class 5: Finding an elevated footrest cause you read somewhere that this can help, contemplating hospital visit"
There were also some differing views on why you take your top off - with some suggesting it's due to temperature.
"I do it when I overheat. It doesn't happen often during the winter but happens a lot during the summer," explained one person.
However, others claimed it's actually to avoid getting any mess on their clothes - and a worrying amount claimed they have to immediately go for a shower.
"I'll usually opt for the complete strip down procedure. A courtesy flush might be in order as well. A post shower is a given in this situation," wrote one Reddit commenter.
Another added: "It's insane to me as a woman, but my best (male) friend gets totally naked and has to shower afterwards. I don't think he's ever shit in a public restroom. I was absolutely incredulous when he explained this to me."
"Man sometimes I turn the shower on and strip before I even sit on the toilet, knowing full well I'm about to make an absolute mess of myself and will need to be hosed down immediately afterwards," wrote a third.
While the vast majority of the people confessing to stripping off were men, there were some female confessions.
One woman put: "Wait undressing when the shit is getting serious, is just a menthing??? I thought everyone does that."
