WHY ? are we who we are ?. (part 1)

Well it s something i have given a lot of thought to ,Why do i love being Zoe , wearing female clothes and underwear wearing full make up ,painting my nails and being tottaly en -femme , something i do most days , not very often i actually dress as a male now , normally as soon as i get up i put my bra ,stockings and dress as a female for the day full make up and in general present a female persona ??? .What causes me to feel this way so strongly that i prefer to dress as a woman rather than the genetic male that i am mmm ?.For me being Zoe is an important part of me as a person , i do no harm to anyone ,I feel better as a person as zoe , i feel natural as she too , to me being female is something if i had the chance i would most definatelly take , then i have built a life around my maleness so to speak (i.e. family wife etc . ) but have the added bonus that i do have the choice of being who i am inside even though in some respects it is a facade on the outside because i am still genetically a male ( well i do have a 38 b bust ) but that is due to treatment that created the bust not that i wouldn't be without them now , so i fill my bra's natuarlly no chicken fillets for me , though i did use them in the early years to create the shape , sexually i am bi in nature and i have had my little bits of excitement both as male and zoe , but sadly not very often , but i as a person am happy with my lot i dress and become zoe most days which my wife knows well not that she couldn't as she sees me most mornings getting dressed and luckily enough she has gotten used to me being zoe and doesn't bother her at all ,in fact i wear lingerie and make up more than she does .Sexually not a lot going on between us but that is due to our health not for the want but love is a strong thing and we deeply care about each other we are soul mates , and me being en femme is part of my life that she has accepted and helps me with she buys me underwear make up dresses and skirts and blouses so she is fully accepting .So i realise i am very lucky some of us girls are not so and i do appreciatte that fact .
Sexually zoe is Bi sexual and i have had my fun (sucked a few cocks been anally fucked not so keen on giving but i do like to recieve and i do love giving good head and i have done both as male but i have done it as zoe too ).
My first experiences i shall put into part 2
