Sometimes a small lie can have a huge effect, while a seemingly large lie has no effect at all. I think it's hard to know which is which. Also, how do you gauge what you do affects your SO? The time and money spent on crossdressing has a direct impact on your SO's lifestyle. It can bankrupt a family if not kept in check. The chances of being caught are pretty good too.
I just think the stress that a CD puts themselves under by keeping these secrets cannot be good for themselves or their loved ones.
