How has an affair affected your marital sex life?

If you have had an affair, or more likely been cheated on by your spouse or former spouse, how did that affect your sex life (assuming you remained together for at least six months after the affair became known)? Did it ever rebound to be as good as before? Did the affair actualy make your sex life better? Did it affect how you have sex (types of positions, frequency, mood, intimacy)? Do you ever fully recover from an affair in the bedroom?
