Happily married but different sex drives

Happily married and have good sex 6 to 10 times a month. I have always been a very sexual person and my wife goes in spurts. There is no kinky exploration on her part besides sex. I am appreciative of that but always keep wanting to push our boundaries. I have been wondering if I keep trying or find some other woman in the same married sexual situation that would like to explore together. Love and attracted to my wife but need to know to move on from my overwhelming sexual desires or what is the alternative?
