I wouldn't want to marry someone who was so shallow/narrow minded they would do a 180 degree turn and run away from someone they proclaimed they will "Love till death do us part" because of my birth gender. It's like them saying "I love that you were born with a vagina" not that they love -you-.. I have a feeling anyone I would be attracted too would also accept this part of me. To hide something this big from my life partner would slowly eat at me and I would live in fear of the day they somehow would find out. All it would take is a doctor one day discussing a chest xray and noting the extra ribs. Oh that's right you -could- get your ribs removed too and get....... where does it end?
I agree with Annette, I hid I was TG/a woman for decades, I'm not going to start hiding my past now.. For me that is jumping from one closet into another. Living in fear that someone would find out I am trans to living in fear that someone will find out I am trans..
