Now, I don't know about anyone else but if I'd set up shop with a nice looking lass with a nice job, I'd be more than a little gutted to find that she wanted to sack it and become a brickie called Derek. I wouldn't have married Derek and I would be unlikely to be very interested in taking up gaying in order to keep Derek happy, either.
Some people select their spouse for deeper things than what they look like (when young) and their current job.
Hence some people end up divorced and other couples survive and thrive no matter what is thrown their way.
I appreciate that - but the sex of your spouse is quite important to most people.
Is it? Or is that what you've been conditioned to believe?
Is a spouse not just, to use modern terms, a BFF? Who you trust and share intimate moments with?
Be that cuddles and kisses or full on BDSM action, finances to the final decision to let you go.
If so, it doesn't really matter if they have operations to make them in to a dolphin, they are still your spouse and your BFF.
