A bi man with a wife and a family could very well be having sexual encounters with men once in a while with the agreement of his wife (who could well have her own stuff going on too) and it could be a very healthy thing in what is a fulfilling relationship for both parties.
People have been advocating for marriage contracts that are a bit like the CC license, where you can pick the parts that you agree on.
(There are some automatic protections in the event of a separation.)
I wasn't speaking directly to that, moreso that secrets have value. Some people would reveal their secrets rather than be controlled with them, others will define the value of their secrets by what they're willing to do maintain them.
This remains something quite a lot of people want to remain secret.
