I have no wisdom.
But I know this, I didn't marry a vagina, I married a person and she calls herself Mary.
Mary has earned unconditional acceptance from me so many times over. I have no desire to change her. Sometimes parts of her pisses me off. But she is human and I am human and I am plenty sure I have more parts that piss her off than she does to me.
She didn't marry a penis. She married me. If in the future I don't have the penis, well, I hope she is still there loving me.
Some women they get hysterectomy operations later in life. Is that a reason to ditch the woman? No. She's not suddenly not the person she has always been. She's not a womb, she has one currently and it gave us our son. My son came from my testicles. If some day I am able to ditch the things, he doesn't stop being my son. And I am 51 and done the procreation game. I don't need a means to fertilize females any more. I was glad to make my son, and enjoy every day I think about him. Having him was the pinnacle of my life.
My marriage will not be lessened from being unable to have male to female sex. I don't need to be riding her and waiting for the OMG moment when I do a singularly male function. I won't lie, I like the sex act. I like a lot of things though. And it is just one of them. It was useful in the early years, but today, my life has needs, and they don't require a penis.
My wife has needs, and thankfully she doesn't really need that penis any more than me.
So far, I can say things have been beating the numbers.
When I come to bed, I am not coming to bed as anyone other than me. It's my bed, it's her bed, it's our bed. If we only sleep in it, that is fine.
I don't recall my vows mentioning remaining a male at all costs. I recall love, honour obey cherish sickness and in health, till death. I don't recall being miserable.
And what is it to love a person unconditionally? Generally speaking, unconditionally means you don't subject a person to conditions.
And while you can spin transition as a condition, the thing is, a lot of things go best if the go both ways. Forcing a transgender person to remain as they are, is a cruel abuse of power, and tends to void the spirit of unconditional love. It isn't easy to honour unconditionally to obey unconditionally to, cherish unconditionally, to accept the good and the bad unconditionally.
I have never forced my wife to be anything she doesn't wish to be. I can only ask the same.
I can only hope your wife loves you as equally completely.
Too many people though, they marry for wrong reasons, flimsy reasons, and in the end, the marriage was never really as solid as it might have seen.
Live long enough, and eventually life will keep throwing challenges at you. 28 years later, and I have seen most of them. And my wife has bested them all.
I hope your wife is her equal.
