To share a bedroom or not?

[Beautitude]

Just wondering about people's experiences in the area of bedroom sharing? We are expecting our second son in October and although we have a 4 bedroom house and the boys dont need to share a bedroom i was wondering whether it would be beneficial for them to share a room? I guess its quite an individual thing for every child but i guess when i was growing up i always wanted a sister so i could share a bedroom with her so i was wondering what people's experiences are with their two children sharing a room. Also what age did you start your two little ones sharing a bedroom and was this too late or too early in your opinion?
