And, as I have said repeatedly buy you seem unable to grasp, for me, it’s about what happens AFTER we have emotionally committed to each other. If he and I have decided to be monogamous. Before that I care not a jot who he shagged.
I'm the same. If DH left me, or ran off with someone else I would be devastated. Totally shattered. I love him absolutely - he's my best friend, the love of my life, the best thing that ever happened to me. Cold isn't a remotely accurate description of our relationship.
But that is now he's with me. Who he was shagging when he was a jobbing actor on tour in the late 80s is none of my business and any scandalous stories he tells me don't bother me at all. Equally, he isn't fussed at my having had a bit of a wild youth. We had fun, experimented with loads of different kinds of sex and now know that what we want is each other. If you don't want that OP, that is fine, but it's total nonsense to say that no one else can have both mad fun meaningless sex and relationships or that people who don't solely insist on snuggly romance novel sex are emotionally deficient.
