Pros:
ready boob/testicle access

Cons:
human noises disturbing your sleep
less space
passive aggressive duvet
shock cold feet touching

I'm struggling to adjust back after a week spent sleeping alone. But the lists above definitively show that there are more cons than pros to this arrangement. That's not even my opinion, it's just simple maths.

Do any couples outside of 1940s American sitcoms and the almost dead actually have separate beds? Genuinely thinking of sleeping in the bath from now on.
