Or on the woman's part? "Oh, I just realized I'm a lesbian! Please don't leave me!" Depending on who was first. But I'm more inclined to this as you can just fake being a lesbian just like that, while transitioning takes a lot more effort (as per the picture - in this case also including fake tits).

Probably not hard to fake being a lesbian if your wife has a dick.
