Pretty sure everyone here knows about Brittany and Abigail Hensel, the conjoined twins. Abigail got married. It brings up so many questions. Abigail is the one on the right, in case you wanted to know. But so many questions. Does Brittany just, well I guess she doesn't have a choice but to just hang out when Abigail and her husband decide to go places, have dinner, etc.. And what does Brittany do when Abigail and her husband get down and dirty. If they share everything below the chest, I doubt she can just ignore what's going on. Does he get to hear them go off in stereo? Does he only get to feel up the right side. That shit has to be awkward as hell for Brittany. On the other hand he can technically say he got to do twins at the same time. And shouldn't he be standing on the other side?
Each girl only controls one side of the body (but instinctively coordinate when it comes to moving). Which means Brittany's holding the bouquet. But I believe there's a pragmatic reason for the observations you note: I don't think the husband can legally marry both, and Abigail being the wife is probably the compromise settled on, while effectively they're in an inseparable threesome.
Fun fact, by UA logic no job should accommodate them and they may not actually exist since 99.99999% of people don't have two heads.
I think speculating publicly about their sex life is fairly weird. Apart from media attention due to their condition they've generally tried to live normalish private lives, they aren't celebrities who have pursued fame and can be argued to have opened themselves to all the public discourse that comes with that.
And at the same time, it's 100% their fault no job will accommodate them, and they need to put in more effort and improve their work ethic. Not existing is not a valid reason for being unemployed.
I do not have the fortune to know them personally to ask, so I will just be happy they enjoy the benefits of marriage in their way.
