Because of the way neurotransmitters work on the brain, someone who is manic can also be hypersexual. They truly may have little in the way of reasoning - instead psychosis rules in this state. (OR they may become paranoid, or have delusions of grandeur, gambling addictions or other manifestations of psychosis, and not commit adultery, but go off the deep end in other ways.) This is when the brain is overstimulated by too many neurotransmitters.
The opposite is also true. If a bipolar person gets depressed, they will probably lose all sexual desire or libido. Since most people, normal or not, do not like to be like this, it seems unlikely a depressed person, (bipolar or otherwise) would purposely choose to be in a state where they have no interest in sex, even in a marriage. Again, that is caused by neurotransmitters, this time a lack of them.
I minister to bipolar people. I literally have not met one person who has not run off on their spouse, or been divorced by their spouse for manic behaviour. Many of the women have lost custody of their children, and it grieves them to no end. One woman told me she has no idea what she did while psychotic, just that when she calmed down, with the help of meds, her husband was divorcing her and she had lost her baby and 3 year old son. She continues to be distraught, even though her children are in her teens. She says bipolar disorder ruined her life.
Bipolar disorder is just so weird. It is hard to believe that someone's brains can be hijacked by chemicals which are normal in the brain, in the right numbers.
Maxwel, I would refer you again to the side effects of Mirapex, used for Parkinson's disease. People on it displayed bipolar manic symptoms while on it. Apparently the drug works really well to stop the symptoms of Parkinson's, including the shaking. That is because the drug targets the lower brain stem, replacing the neurotransmitters that are not getting to that part of the brain. But because bipolar disorder occurs in the top part of the brain stem, the neurotransmitters were "leaking" into the top part of the brain stem, giving people on Mirapex the symptoms of manic bipolar disorder. Some people's lives were literally ruined due to gambling or adultery.
But when they were taken off the drug, they returned to normal. They could not understand how they could have acted that way. That is what people with bipolar disorder suffer with every day. Although the meds help, they have a huge list of side effects, which is why they, along with schizophrenics seem to go off their meds. Until the reality of what is going to happen finally sinks in after repeated hospitializations, and destroying their lives.

Sorry I can't find the on-line video of the whole show. It was quite fascinating!
As for whether committing adultery in this state is a sin, all the people I work admit it is. They don't know why they did it, but they do recognize it was wrong, and a sin. One Christian woman, who lost her daughter and marriage, regrets terribly what she did. But she still does not have an answer as to how it could have been stopped, when she did not have a diagnosis, nor a clue that she was mentally ill until the dust settled and the bad deeds were done.
