We formed our group among married swinging couples who we met through the traditional ways and became friends. We shared the common desire to be uninhibited in the way we engage in activities, including playing alone and playing bareback. We got together and all pledged not to play outside of the group even with condoms, pretty much upon penalty of death. If you want to play outside the group, you can leave, no questions asked, no recriminations. No one has left thus far. We were all tested twice, and have free from the usual worries of swinging. You might think that the temptation is there, but with the quantity and variety of sex available to each one of us, the temptation is less than for a monogamous vanilla couple.
