I need to clarify the gist of my comments on Psychosexual Politics.
1. Anyone who breaks the vows of fidelity with a spouse has committed an ethical transgression. It is grounds for divorce.
2. The transgression is personal, a matter to be dealt with by the two parties involved.
3. No spouse should be entitled to ask the government to investigate whether their spouse is being unfaithful. It is a personal matter, not a public matter. Conversely, the government should not take it upon itself any such investigation. If, in the course of investigating another matter, should the government come across such a transgression, the government should leave the matter lie. The transgression is personal
4. Sex between consenting adults is legal---period. The nature of the sex or whether money is involved is irrelevant. People often pay to entertain themselves. Whether it is appropriate for anyone to have sex with another person, with or without money being involved, depends on ethical principles such as fidelity to a spouse, abstaining from sex with someone else's spouse, etc. All of this is personal.
5. Tax money should not be spent to support any kind of sex police, with the exception of minors, nonconsensual sex, and public sex.
6. A betrayed spouse should be entitled to deal with a transgression of this sort in their own way on their own terms, not have the government create a public spectacle which just magnifies the grief and punishment for the victims (the spouse, children, and others ).
