My nesting partner and I have been together for many years and live together. We're a bit new to enm. One "boundary" we have is to not have sex with others in our shared bed. This helps us keep a protected space for our relationship. Sex with others is "anywhere else", but this makes hosting a little awkward. So...

1. is this a semi-common arrangement? How familiar would other partners be with this boundary? Might this seem surprising and annoying?

2. How have you dealt with the "others in our bed" issue? Was it uncomfortable at first, have you kept that boundary in place, or how has it felt to allow others in?

Any other words of advice - supporting or challenging this boundary (and the thinking etc behind it)?
