Married to a lovely sexy lady. However, humans are not biologically monogamous by nature. That's only caused by the historical religious marriage relatively new in modern history. Like giving a diamond ring. Traditions do not determine biology. We get off by seeing the other aroused and sometimes when your are the partner, you cant see it in the same light. Additionally, everybody agrees that the best sex is strange sex at least initially. Life is too short to bored in bed. Wife has a job that requires public image untarnished so she plays more discretely.
UPDATE: Divorced...lol
