hippy bi couple seek same for longterm friends with benefits

We're a bi-ish hipppy-ish alternative couple together for 24 years. He works as a diversity adviser for a public service provider and she is a carer. We are not looking to be a 'notch on a bedpost' but would prefer a long-term friendship based on more than sex and will offer more than sex in return. We are very happy, secure and trusting, both in life and in our relationship and if we find a couple to have as friends with benefits, would like to think that we can eventually see each other in all possible combinations.

If you are a couple who are relaxed, have no relationship issues, and would be happy to have a mutually exclusive arrangement we would love to hear from you. We have no preconceived ideas about what you should look like, what abilities you have, or what your cultural, ethnic or religious background is but racists and misogynists need not apply
