Hubby and I have been together for almost 30 years. I call him hubby but we are not legally married, I wear a wedding band and we don't go around announcing we aren't married (cause it's not anyone's business). When we first started living together and went to visit his parents, we offered to sleep in separate rooms as they are super conservative. They, however, had no problem with us sleeping in the same room. I'm pretty sure they have forgotten by this point that we aren't married. My parents never had a problem with any of us 6 kids, sleeping in the same room with our significant other. I certainly didn't have a problem with my son sleeping with girlfriends and/or his fiancee any time they stayed with us. We pretty much go by the my house my rules premise. It certainly wouldn't stop us from visiting someone if they didn't want us to sleep in the same room, frankly after almost 30 years of sleeping together, a night without fighting snoring and kicking isn't a bad thing.
