A and C have sex.
A Review of Irvine Welsh’s “The Sex Lives of Siamese Twins”
It's probably weird, but again they're used to it. If any of these conditions are absent, then any resulting sexual action is non-consensual. Born via caesarian section, these twins shared an anus, genitalia and three legs. Such a person is not in a position to validly consent to sex, since she is not in a position to know the relevant facts about the act and so she is decisionally capacitated. But it seems impermissible to involuntarily expose someone say who is in PVS or otherwise does not consent to having a risk imposed on them to a non-negligible risk of serious harm. Similarly, if A and B are minimally fused, as with Chang and Eng Bunker, then it seems implausible that B and C would count as having had sex. It had never occurred to me that conjoined twins think of themselves as soul mates, and may feel much less drive for connectedness — both emotionally and physically — with another human being.
