I guess if you have been reading this website, then you now know that crossdressing is not just a "phase" that will go away - most of us thought that it would go away after we were married - WRONG - it NEVER goes away - so if I were you, I would try talking about this with your SO - I would not shave any body hair or do anything to your body - this is a real good way to piss her off forever.
