The K.I.S.S. approach has appeal. I'll think that over.
Communication about sex and feelings is the weak point in our marriage. I don't think either of us grew up in an environment where we learned either the skills or vocabulary to do so easily. We're both intelligent adults, so we manage, but it often begins to approach the critical stage before we begin talking and there's a lot of groping about to express ourselves clearly and then to create an action plan.
I, in particular, have difficulty telling her "I want X," because it feels selfish. That's my own hang-up. The acknowledgement of the need to communicate is something that impresses me about the poly community. It's a skill that I know I have to work on.
And oh, yes, this discussion must certainly happen well before pregnancy. One paradigm shift at a time. But something will begin tonight.
