I'm pretty sure that the reason most of the guys that do not reveal before marriage choose not to disclose because they fear it may be a deal breaker. I know some will deny that but why else would you hold it back? Think about it. How would you feel if your fiance/wife held back something about herself that might change your mind about marrying her? This is especially an issue if, upon reveal, it turns out that in fact the issue/crossdressing would have been a deal breaker but now you are already married, have a house, kids, etc. It's patently unfair and selfish to hold it back. This seems so obvious to me that I don't understand why this question gets asked so often.
