If I'm reading what you seem to be saying....now that you did it....you want his parents to just allow you to sleep in the same bed???? IN THEIR HOUSE UNDER THE VALUES THEY HAVE......in other words, it sounds like you want them to change their values because you did it in their house????

IMO......what you do in your own private time together is your business.....what parents values are is their business.....& nothing is going to change. Parents are entitled to have & to hold their value system in their own house. My daughter lives with her BF......but you can betcha if they come to my house....they have separate rooms because those are the values I HOLD. Sometimes you just have to accept some things are what they are.....DBT calls that radical acceptance.....just deal with it the best you can.

It doesn't change how you feel for each other.....tension is tension....there will always be things that cause tension in our lives sex or otherwise....do learn to deal with it because it's just part of life IMO.

I may have gotten it wrong what you were getting at, but this seemed to be the direction your words were going.
