Help! I Love S*x, But I Can't Stop Che@ting on My Good Husband - Woman Cries Out

I am young and successfuland have been married for 6 years. My husband is the best husband one can wish for and we have healthy s*xual life.
But my only problem is the fact that I am constantly looking for s*x outside my marriage and living in this perpetual guilt thereafter.
I have tried keeping away from men not once but infinite times, but end up straying always.
How do I deal with this situation?
