No, no, no!!! No officers. lol
When I first started swinging and having sex in public, the cops that came across me were always polite and my man would make a joke and they would say "carry on" or something along those lines. I even had one ask if he could watch. We ended up seeing him at a swinger party a year later or so. Totally cool. He invited us to a later party where there were several police officers including other women.
Now, I can't say the average cop is so friendly anymore or at least in my experience.
