What have you done that you have never told your partner?

Went with a group of girlfriends out of state to a bar where the Chippendales were performing. I ended up on stage, and after the show, I fucked three of the guys. My husband never asked, and I never told him. I would have if he asked, though.
Hah - how did you end up hooking up with the guys after the show? Get invited backstage or meet the guys out somewhere after?
 
giving blow jobs at Kohl's dressing room, and watch their wife get pissed as she waits for him to come out of the dressing room.
