For those of you participating behind your partner's back, getting caught is likely an inevitably, what is your plan if/once it blows up in your face?
The consensus I've gathered is that a decent amount of the clientele is made up of people in monogamous agreements. As careful as one may be, all it takes is just one notification at the wrong time, or maybe a database leak or worse a law enforcement encounter or catching something like HSV 2 to completely derail significant parts of your life.
Obviously, you're likely being as careful as possible, but it only takes one fuck up. Maybe your partner will be more forgiving because there were no feelings or maybe they'll feel worse if they are anti companionship.
I myself wrestle with this question and usually conclude that it's disingenuous and not worth it, so it's not from a place of judgement.
