Sex with unmarried women?

So I was in S Dakota the other morning. I heard on the radio no I duno what station or show.

But they were saying that in Michigan that it is illegal to have sex with an unmarried woman.
So if she is married would it matter if she is married to someone else? LMAO

I know that Maryland has a Sodomy Law. So all forms of non-vaginal sex are criminalized. No way I could ever live in that state
