I have friends who are bi-sexual and a couple of them have had or are in dual relationships. Whats the secret? Love, trust and communication. Not every secondary relationship works out for a couple and I know that some couples do not stay together after exploring secondary relations. I would say that if you and your husband are interested in adding another woman to your relationship; be very sure of what the two of you have for expectations. Like I said before, not all marriages survive such encounters. Just remember that it's one thing to fantasize about this type of relationship but the relaity of it might not be so appealing in the long run. Good luck in all that you do :)
