We started out as a dating couple - after we were "steady" for about a year, I was away working, and my then girlfriend, now wife cheated on me - it was full on sex, with another guy in a car that she went on a date with in my absence. She cheated on me on, and off over the next five years, all full-on sex, no just teasing around with blowjobs or handjobs.
She cheated on me at least six times after we were married - also full sexual encounters. After our first "open" hot wife encounter (unplanned), which was full sex, she farted around with blowjobs and handjobs for a while, because of guilt feelings. That passed in less than a year.
