Do sisters and brothers need separate rooms?

Growing up my brother and me had the same room till we moved out.

In college talking with friends it seems like we are the only ones who were not separated as teens.

Think I'm damaged for still sharing my room with my brother?

Do sisters and brothers need separate rooms?
Yes they need separate rooms
No it's fine sharing a room
Only fine for step siblings
Why not share a curtain separating the rooms is enough
It's fine just use the bathroom to change.
