My marriage is OK.. Not great, not exciting, but nothing to complain about. I miss having butterflies in my tummy, that electric feeling of falling enough and first kisses. Is OK good enough? I know it is selfish to think this way but I can't live the rest of my life with a boring OK.

Who doesn't miss that feeling of butterflies and first kisses but those things realistically don't last. You can however maintain the warm and giddy feelings by putting in effort in keeping the passions alive, not taking each other for granted and to always be there for one another. Personally, I'd take the feeling of certainty, stability over a temporary rush of emotions any day.
