Listen to what you're actually saying.

"My wife respects my boundaries and rights to privacy only when and where it's okay by her, but doesn't even hesitate to violate my privacy and the boundaries I set and communicate to her if she thinks it's not okay. She's not controlling. I promise, your honour, it's only if it's an inconvenience or a problem to her then she'll fucking break into the bathroom."

Your kids should not be taught this type of disregard for personal boundaries and privacy. The example you and your partner set in their formative years will wire their brain to accept this as normal. Do you want your daughter, if you have one, to end up with a partner that treats her the way your wife treats you? Do you want your baby girl to have a man break into the bathroom and yell at her because she dared lock the door while she showers, and think that's normal and healthy behaviour that she should tolerate? That the boundaries she sets for herself means nothing if her partner has an issue with it. Really?

You need to figure out why your me-time is such an issue to your wife and have a serious talk about it. This isn't healthy for anyone involved, least of all your children.
