This has nothing to do with the OP's question. Obviously, a person has a right to ask people to do whatever they want in their own home...
But...
I have to say I am really shocked at how many people find my lifestyle to be immoral. I've lived with my BF for years, and I
never have any intent of getting married again to him or anyone else (been there, done that, never need to go there again). I also have no intent of ever being with anyone but him ever again.
We are not wild sex machines, sorry to dissapoint those who think an unmarried long term couple can not "hold off" for a few nights.

Um...In fact, and I'm sure this is TMI, we are probably less so than most of our married friends because we get up early, have a long commute, work 8 hours, have another long commute, come home, he makes dinner while I train our dogs, take care of household duties (which are all shared), relax by watching tv and quite frankly by the time we get to bed, we are too tired to be the ravaging love fiends that people seem to think we must be because we are "living in sin".
It's not about sex. It's about accepting that we are not married and never will be. All of the children in our families know that we will never be married and they know we live together and sleep in the same room (except for the ones who are too young to even notice such matters). If you want to raise your child to think that we are horrible, sinful, immoral people than by all means, go ahead. That is your right. But I also have the right to not want to stay with someone who insults me and my morality.
We live in a committed relationship. We are not religious people so for us aside from the legality of signing the papers, we are essentially the same as every non religious married couple we know (except, oddly enough we fight less, and our relationship has outlasted at least two marriages of people I know). Our married friends (and unmarried friends but primarily married since most of our friends are) routinely ask us for relationship advice.
Yes, respect does go both ways. I absolutely respect other people's religions. I get mad when people don't respect other people's religions. But that does not mean I have to be willing to change my life just to stay at your house. I'd stay at a hotel, but I also tend to think that someone who can't accept me for who I am and always will be is going to want me to stay with them anyway and probably would not want to be friends with me.
JMHO.
