Just be honest, as you have here.
Make sure potential friends know that you're not newbies though, that way they'll know in advance that your 'no intercourse' rule is for real and not something that could change if things get hot.
This way there'll be no confusion later.
And I, personally, have enjoyed going into an adventure with another couple knowing in advance there'd be no intercourse with the other spouse. Hey! At least for me, intercourse is simply the finale, the flirting, kissing, petting, and oral is the feast!
You'll find a lot of couples who are into the same 'soft swing' thing. Maybe not so many here though.
Good luck and enjoy yourselves..., your way!
