Married 27 years, still married, no signs anything will be changing in that detail.
Life though is change.
My wife has stuck through with more than a few hard challenges, I think shes either a glutton for punishment or a hardcore not quitter type.
I think she'd have left me a long ways back if she was inclined to do so.
But still, there is a big difference between leaving a man and leaving a no longer male person.
And while marriage is not all sex, and if you ask most couples they hardly have sex at all in many cases, but let me tell ya, the moment your sex life is not being delivered via her body, it sure as hell makes a damned big difference.
But when your sex life requires her to do to you, what you normally do to her, it can get complicated. Maybe she doesn't quite like giving ->-bleeped-<-s, but giving another female oral well its not something the average woman expects to do in a hetero married existence. She's used to laying back and you using your magic fingers on her, not her doing that to yours

In my case, I have had a VERY active sex life in the last number of years. If you measure frequency, I was likely getting it more often than the rest of the thread combined for the last few years

But, I am not really sure what that was all about either. I have thought my body was over compensating for something. I'm not in the greatest of shape either, and some days, just being able to finish the act, it is a lot of hassle for me let alone my wife. And she's not in the greatest of shape either. Life with me has not been a picnic.
My wife and I, we have both resolved that A, we love each other more than life. B, we dread losing each other. C, we both really would prefer my sex drive gave it a rest as she really doesn't want it any more than me and currently I would rather it would shut off and stay off. I figure if HRT turns it off, we both win. I have no trouble sleeping next to the person that means the most to me. She is not just her body. And inasmuch as vows go, we did after all say for better or worse, sickness and health forsaking all others, till death do us part. There was never any mention of sex, or the specific method of how to get off.
My wife and I have realized, 'we need each other'. Our lives, divorced, they basically roll over and die. Financially we suffer, and we end up alone, and we have no one there to laugh with. We got married because we wanted each other. We'd done the parent thing. That stage is completed. Our son is an adult so we have no entanglements there.
We just the other day bought some tops from a company we like via their online store. Simple tshirts. It was handy we are the same size. She stated though, if they are really nice, she reserves the right to re order and get her own set

I don't mind, she is always spilling stuff on her tops anyway

But it is nice we can at least have the ability to enjoy the fact that we might be able to share clothing in some cases. I am not sharing lingerie though

She can get her own

But I feel so deeply sad for all that have marriages that simply can't come through unbroken.
I think too often, the vows in the ceremony don't mean enough, the sex means too much and people are often too set on seeing the shell as being who we are and not the person inside. Kids often make things too complicated, or the couple simply has not survived enough trials earlier to make it strong enough.
