While my wife isn't interested in crossdressing bedroom play, she is more than happy to let me go out, more than happy to buy me dresses.
We have tried some kink, but it wasn't really our thing, it's more a distraction to fun.
But yes, she knew my interests before we got serious, and was okay with it.
Those that hide it tend to get one heck of a slapping (mostly for dishonesty etc), sometimes with a divorce order, so always best to be up front (just not on the first 5 dates)
