I am perhaps not typical, but in my relationship, make up sex goes both ways. In fact, sometimes the sex precedes/causes the making up. LOL. I will have sex with him when I'm still angry with him over a mistake he's made: partly because it's just fun, but also because it helps me let go of the anger. I do use sex to help make it up to him when I've made a mistake as well. I admit I made a mistake and tell him I'm sorry and then offer to make it better. Sometimes he pretends like I've hurt his feelings just to try to get me to make it better.
