Interesting that you would not make sex between a prison guard and their prisoner a crime. I certainly would not make my examples 1 nor 2 a crime. And I tend to agree with you about 3, the teacher and of age students.
But alas the courts tend to defer to the legislature and those who want to control others have found that majorities often are willing to support laws against sex they do not like. Or maybe I should say courts tend to defer to legislatures except when groups who vote Dim come before them and the higher percentage of the group that votes Dim, the more likely they will have special exceptions to the law carved out for them.
And the courts are all over on issues like this. Sodomy laws are unconstitutional, but I bet laws like the one we are discussing have a shot a being upheld.
