The other thing i would add is that physicality and sex specifically vary widely between couples.
Some people say "there is no way i could be married to someone i was not sexually attracted to". In my opinion, that ignores the simple fact that sexual attraction changes, ebbs, and flows. Almost anyone married for a long time sees this. But, you often keep having sex in spite of this. Intimacy becomes a confirmation of the rest of your love and connection together.
