I'm not on OKC, so it's difficult to say for that site, but I have no problem if my profile is filtered out like that. If a woman isn't interested in a married guy, then I'm fine if she never sees my profile. I put it, very clearly in my fetlife profile that I'm "Married to someone not on fetlife" and I elaborate in the "about" section to say that it's not just that my wife isn't on the site, but she actually doesn't know I am. If some girl has a problem with that, then I am 100% good with her blocking me. I only want people who are ok with my situation and won't go crazy at the idea that I'm married.
Like I said in my reply to
@billyS, it doesn't matter so much to me if people don't see my profile. I meet people, live, at parties and munches. While we are talking I do mention I'm married, and the conversation goes on from there. I am certain that it's an easier sell when the person is talking to me in person and we can discuss it. I know that people who might have never seen me with that on my profile are more open after a conversation. But still, I have no wish to trick someone into that conversation. If it limits the people who are available to me, then so be it. There are still plenty who are fine with it. Quite frankly, some are even into it.
