In the past I was invited to a game of truth or dare, where you need to either answer a question truthfully, or perform a "dare", both of which are set by other players. I was selected first, and as I did not know almost anybody there, I asked this girl what was her best friend. Then everbody laughed, as this question was too soft, and the goal was to ask more spicy questions. I was embarassed at this.
Then months later I was invited to another game with a totally different group. I thought I was prepared, so I asked to this girl I didn't know what was the color of her nipples. At this, she became extremely embarassed, and so did I. Apparently this was too much personal, or the group was expecting less naughty questions. I really don't know.
My question is: how can I participate in this kind of game, without embarassing myself or others?
