I have only told one guy friend about it and that is because he seemed to be curious about the lifestyle, if just in a general sense. I don't think he has had a problem with it but it certainly has let him know that we are not your run-of-the-mill couple. We don't change the way we are around them and I think that lets him understand how normal things can continue to be.
It definitely is a risk that is not always worth taking though. I think if you need to have someone to talk with about your lifestyle, the best way would be to make some new friends in the lifestyle.
Fem D has told her best girlfriend, but she tells me that they don't talk about it much. And, although this GF seems excited about what we're doing I think Fem D is worried about overdoing it since we're not looking to play with her. It is just an update sort of thing, I think. So far, so good there.
You really have to know your friends and their backgrounds to take this kind of chance. We meet people everyday and think we are close to them after awhile, then we find out about their biases. We want to have friends in all areas of life, but we can't just tell anyone who's our friend.
