Should couples sleep in seperate beds ?

I think it is a personal preference actually. Bu then again it could be a religious reason. I know in some religions they only sleep together when it is times to make babies. Personally, I don't think there is any reason to be married if you are not gonna sleep together and have fun if you know what I mean! lol :)

depends if they can share the quilt or not! my girlfriend oftne wraps herself up in the duvet (which is why i keep my emergency one at the end of the bed ;)hehe) Also if they're not looking to have kids it could be a very effective form of contraception ;)

If that's the way they want to sleep, I see nothing wrong with it. Maybe one or both of them are light sleepers and were bothered by the other person moving during the night. My ex used to snore loudly and I would end up in the spare bedroom many times because I was unable to sleep with all that racket going on.
