I am bi-curious and have been with heterosexual couples for lovely threesomes. I also have met a msrried man or two on the side, but try as I might, they would not bring the wife along, thus I deducted that the wife did not know of the husband's bend....of submitting or whatever. I still would love to meet an hetero couple where the husband is at least bi-curious and ready to give me a nice BJ while I get to fondle and play with his lady. True, you also have couples where the husband is bi-sexual. Such a couple I might not be willing to meet in that the husband might want to go....where i am not willing to go.
