Have you played strip poker with a group? I played a kind of strip game in Asia with a group of people. It was fun to see people when they ended up showing some or all of their private -- like which girls had hard nipples and which didn't, and which guys were hard and which were not. Some people got excited, and other got shy or nervous.
I used to play poker with my daughter in law.. Loser had to do embarrassing things.. I purposely lost so I could be humiliated in front of her...hahaha
