The "change genders" question actually is an agreement that dh and I came to once.

We were watching a program about a woman who was once a man, and her wife dumped her when she came to grips with her transgender status. The wife was all, "I still love him, but I can't become a lesbian for him!"

So we discussed it and decided that we'd become gay/lesbian/male/female for each other if that's what it took.

In a consensual, reasoned-out way, of course. Not if the issue came up as "I want a divorce. And I'm gay," or anything like that.
