Years ago I came out to my wife in the most unusual way: she caught me trying on one of her skirts. Cardinal sin, I know. But I had no choice in telling her at that point, to which she answered "They're just clothes." I tried to dress around her a few times afterward but could tell she was not comfortable with it so I quit doing it.
Since then I've purged my clothes -- always hidden despite her not really caring about them -- several times but always started anew. Then one day she came across my stash and brought it up with me that night. She then admitted she knew about them the whole time and still didn't care that they were mine; "As long as they don't belong to another woman" was her explanation this time. The second time around was definitely more accepting than the first, and I no longer have to hide my things from her.
