Discussion with friends. Very heated disagreement. Unreasonable wearing knickers . Reasonable not wearing knickers

I hate wearing anything in bed. More comfortable sleeping nude. I wear a nighty if I have to share a room with anyone other than DH but never knickers in bed. 😱

Getting into jammies after work - knickers (I may have to take the dog out, judge all you like) .

Getting into jammies after a bath/going to bed - no knickers.

I wear boys boxer shorts (well they're not any boy's, they're mine I bought them for me from M&S but you see what I mean) in bed with a vest or crop top, a new pair every night. The stretchy, cotton boxer briefs designed for men or boys are so comfortable, so much more comfortable than any pyjama shorts because they don't have a central seam and because they're shorts they don't ride up or cut in like knickers can. Plus no VAT on children's clothes means they're cheap.

Men's thermal leggings are also very much more comfortable (and warmer) than women's. I'm 5'5" and on the skinny side, and men's size "small" is perfect. I don't wear them in bed, obviously. Nor do I wear knickers in bed, with or without pyjamas.

What would be the purpose of wearing knickers to bed?! Unless they're sexy ones?

Because it's more hygienic?

MrsElijahMikaelson1 · 22/11/2025 22:03

No knicks for me but clean pjs everyday

Praying4Peace · 22/11/2025 22:05

Deffo no knickers

JemimaTiggywinkles · 22/11/2025 22:06

Either pjs with no knickers if it’s cold, naked if not. My pjs are all very loose so seams aren’t an issue. Change them once a week probably. But I’m definitely gross by MN standards - I don’t change my bedsheets every time I have sex either!

ElaineBurdock · 22/11/2025 22:08

You never wear your underwear to bed. I thought everyone knew this.

Whennovemberends · 22/11/2025 22:09

Yes definitely air it out! I've been wearing knickers all day , why would I want to wear them all night as well.

Branleuse · 22/11/2025 22:09

I always wear knickers because I like to wear my pyjamas for a few nights. Saves on washing

FastTurtle · 22/11/2025 22:09

Nah to knickers and pyjamas.

This. Same!

catin8oot5 · 22/11/2025 22:12

Knickers with pyjamas but not with a nighty!

Muffinmam · 22/11/2025 22:12

I don’t wear them to bed - which is why I wash after every single use. Even if I have a nap I will put on fresh pj’s.

It’s necessary to air it out. It’s also necessary to wash it.

I was told never to wash my vagene because it’s self cleaning. The outside is not self cleaning - you’re meant to clean it!!

RisingSunn · 22/11/2025 22:17

No knickers!

Happyjoe · 22/11/2025 22:18

Why did it get so heated?!

Prob causing both knickers and PJ's, that's one hot bum in bed!

People have some very strange discussions with their friends

I wish there was some way we could immediately react with a laugh!

Happyjoe · 22/11/2025 22:21

I love my PJ's, have about 25 pairs as I wear a fresh one every day and do not wear knickers too, feels wrong and too hot! I have PJ shorts if I want to wear a nightie in summer too. Hate being in bed naked, what if I need to leave in a hurry?!

TellingBone · 22/11/2025 22:23

None of the no knickers lot have explained the air flow question. Under bedclothes and with jamas on what air flow are you on about?

And it's not as if your average pair of M&S 4 for £10 cotton knickers is going to form a hermetic seal around your arse!

Indeed!

My mum always taught me to “give it some air” so no knickers for me!

This!!!

DrFoxtrot · 22/11/2025 22:27

Definitely wear knickers as the PJ bottom seam would go up into uncomfortable places as I move around in bed 😬

hobbledyhoy · 22/11/2025 22:28

Definitely knickers, otherwise your backside would be freezing or at least mine would.

OrangeeS · 22/11/2025 22:31

If you wear your pjs without knickers then surely you’d have to change them every day? It’s the same as wearing the same knickers every day otherwise, in fact it worse as knickers are flatter and pjs have stitching.

Knickers or change PJ’s daily.
Anything else is unhygienic
