When I first came across FDS, this strategy stuck out to me as being unrealistic, but I've slowly grown to understand why it's so powerful for a women looking for marriage. I am stuck on how I would express this principle to men I'm dating, however, especially when one asks for exclusivity on a girlfriend/boyfriend basis. I doubt it would be wise to explain this strategy in full to a date, but at the same time, refusing to explain anything at all seems like it would alienate him. FDS-ers who use this strategy: how do you go about explaining to a man that he won't have your exclusivity until there's a ring on your finger?
