I recently befriended (yes, just friends) a fellow who maintains an open relationship with his wife. I am a terribly sexual person, with VERY few hard limits - but I still struggle with the idea of being open with someone you love. Although I have always been curious - I feel like no matter how good your intentions are to begin with, things eventually will start to get complicated. Focus: Does anyone have experience with this sort of thing? Did it work? Did it fail miserable? Do you know couples who have tried, and failed or succeeded?
