I love your post 2wheel, my wife and I have been in this lifestyle for 7 years of our 12 year marriage and 1 year dating, we actually never gave us a label, we do a few things, with 2 couples we exchange partners, like it is a 3 couples arrangement when we go on a vacation. wife has a boyfriend at anytime, generally 1 regular. and once in a while we will share her, and sometimes though not often I will get a partner.
Sometimes, she will make out with men without it leading to sex just for fun, this video this is from a meeting with one of my friends, who is single.
