I view a "friend" as someone I trust implicitly. Someone I would not be afraid to speak my mind to, be open and honest about my thoughts and feelings with or give the keys to my house. While we aren't "friends first" types we have made friends like this through swinging. Usually by means of sex first, that was fun, lets have dinner and things evolve from there.
I never worry about there needing to be a distance because we have sex together. If I am willing to trust them with all of the other aspects of my life why not my husband. I think friends such as these are even more precious because they are the only friends that TRULY no us "inside and out". Our vanilla friends no nothing of our extra curricular activities.
So my question is deadparrot do your friends really know you inside and out?
