I’m a married man in an open marriage and I am surprised about this too. But I think married women who are open and only interested in a casual FWB arrangement are pretty rare too. I have only pursued married or partnered women to avoid the commitment drama, but it’s tough finding that match.What I've found surprising though, is how many guys end up trying to make it more than what it is. I would think that part of the appeal of fucking a married woman is knowing that there is no commitment expected. But I've come across a few guys who end up talking about what it would be like to start a relationship and ask if I would ever leave my husband. The moment that comes up, I drop them and move on.
