sleep easy, dear, knowing that you are not a freak.
uncommon body maps are still common enough that there are all kinds of diagnoses for it, probably wrongly defined as mental disorders. it's in the hard-wiring, not some odd type of malware installed by traumatic situations.
what you end up doing about this is up to you. advice from a therapist is something i also recommend that you seek.
not because i think you are wrong about your own body map, but because changing your body in any way will have consequences. physical, social, or it may ruin the relationship with your wife.
sometimes, it's a choice between living with one leg or six fingers on each hand, or losing something precious and dear to you.
i know at least one woman here who has decided not to transition in anything other than clothing, because more than that would mean losing her family. it's a respectful decision to endure pain for someone you love. but there are others who've had to choose their own sanity over the wife, nothing wrong with that either.
there are sunnier stories too, of course. many who are staying with their understanding and loving spouse.
but knowing the risks and benefits and thinking it through before doing anything, or choosing to do nothing, is important.
