Well...to not talk about anything else until morning seems like an awkward way to word it...but how about "honey, I would just love it if after sex, we could talk about each other, our experience, our feelings about it, what we liked about it, what we might like to try next time, and how much we love each other...rather than talking about various topics not related to intimacy. I feel so close to you after sex and I do not want to exit that intimate space right afterwards by changing the subject to every day events."
