What is the halachic status of adult conjoined twins?
Background in Christianity SE
I'm Catholic. It occurred to me recently I never bothered to look this up for the case of 1 set of reproductive organs. I tried asking this in Christianity SE Conjoined twins and marriage and sex And then I was accused of lechery LOL. I talk about it in this revision:
There's a deleted comment that said I was lecherous or something unless I was actually 1 of the conjoined twins or 1 of the prospective partners. The comment made it seem like I have a fantasy of having sex with conjoined twins. Lol. I counter-argued that I'm no different from someone in the early 1500s asking 'Can Henry VIII marry his brother's widow?'
10 hours ago I submitted this comment flag quoting Terry Tao:
But it was declined. LOL.

I lean towards closing this question on a philosophical basis since the Catholic Church would not condone such sex that shared the same sexual organs (vagina) in conjoined twins. Common sense tells us that it would not be morally permitted. The sharing of the same vagina by two different males would never be permitted; it is that simple. Medical professionals may or may not be able to inform us as to which twin controls the reproductive organs. Until this is verified, I do not see a positive outcome for any marriage at all being permitted. Finding info on such cases is impossible to find.
Judaism SE
I looked it up in Judaism SE, and it turns out not only is the question almost a decade old and without downvotes but also does it look like no one was ever offended by this question.
