It depends. As the question asks, sometimes if I am mad I will still "give up the goods" but I may not give it all I've got. It just depends on the situation. But usually sex is a good way to feel connected and initiate an intimate discussion afterwards. We do our best talking after sex!
Anger has no place in my sex life. We are not often angry at each other, but if one of us is frustrated, we will cool off and talk it out before sex becomes a possibility. Those are not the kind of feelings I want to associate with intimacy.
