Started ENM/poly about a year ago. I’ve found a partner (A) who fits my kinks and D/s sex needs so well that I no longer feel like having sex with my husband (B - who isn’t kinky by nature. And A and I both really naturally get off on A “owning” me)

I still love my husband (B) very much and I feel bad, like I’ve abandoned him. B doesn’t pressure me, but I can tell he’s sad and doesn’t like how our relationship has changed since my new one started. B has casually gotten together with a few women and casually/infrequently sees one of them still.

I don’t feel good about having sex with B just because I “should.” (I don’t think he wants that either.) I just feel tremendous guilt. B’s still one of my favorite people on earth and I’m afraid I’m inadvertently ruining our relationship.

Any thoughts or advice on the healthiest ways to be caring to everyone involved?
