There are a pair of conjoined twin girls who have recently turn 18. And, both of them have expressed in interest in getting married. The only problem is that share the same reproductive organs. So, it would seem to me that if you have sex with one, you also have sex with the other.

Would they both have orgasms at the same time? Would they rate each others husband on their love making?  If they had a baby, who would be the biological mother?  The more I think about this, the weirder it gets. In fact, it is too weird even for me.
