I'm M60 my partner is F60. We've never been exactly on the same page sexually but have an excellent relationship in many respects. I'm bi and very open minded and She's much less adventurous and a bit asexual/demisexual and now post-menopausal. My concern with opening the 30year relationship is that it really just benefits me. I'm concerned about any implied or actual inequality that might cause and the resentment that could come with it.

Also are there degrees of knowledge in an open relationship? Do you tell your partner every time you interact with another person and exactly what that interaction was? Secrets can be hurtful but too much detail can be troubling too.

What has worked for you?
