Is it somehow weird to share bed with my brother at my age?

Heyo everyone, so i would like to ask you all to give me some opinions about this but nothing hateful please, if you disagree thats fine but no abuse ty

So i live in a pretty small house, but i can't dare to say anything bad. My mom is a single mom of two, me and my twin brother, our dad is a classic story, young girl and boy drunk hook up, he dissapears, she finds out 2 weeks later that she is pregnant, but she is taking wonderful care of us with everything she's got so im thankful for everything we have. So me and my brother we have a pretty small room and ever since we were little we shared a bed and the room, ofc we give each other privacy when we need it like changing or friends over etc.
So i was talking to one of my friends and it was like one of those hour long conversation where you start on one topic and then just shift into endless babling, like youtube autoplay, and it shifted into talking about siblings and how much she hates her sister cuz they argue and fight etc and i just said that sounds harsh, my brother is my best friend we share a room and bed and we hardly Ever argue really, and she got really weirded out by that, said that its super weird and innapropriate for us to share a bed at our age, And i also got weirded out by her comment because i dont really see anything wrong with it, if anything i feel very safe when he is there and its not like i can just force him to sleep on the kitchen tabble or somewhere. And of course we dont sleep naked that would be weird, we wear pyjamas but yeah, we just agreed to disagree at the end, but it left me thinking about it so...

What do you all think? is there any reason why 2 siblings who get along just fine sharing a bed due to living space limitations is considered weird?

Wow okay. Everyone answered with sorta
"its a bit weird but if ur both okay with it, its fine"
that does actually surprise me quite a bit
The tought that it was weird or innapropriate never even crossed my mind, it was always just "say goodnight, go to sleep, wake up, go to school"
so im surprised to hear so many "a bit weird" but i guess if you all think so
