Hedo2forus, we also have been in the life-style for 3 years and have had a hard time finding straight couples. IMO we do not think that there are that many bi women in the life-style, but there are that many insecuer guys. From the 6 sites that we have been members on, it looks like 90% of the women are bi and 10% are straight. We think that there is more of an issue with the guys seeing their wives/gf with another man. So when these kind of couples get in the life-style, a man feels more comfortable seeing his wife with another woman because the husdand feels less intimidated. We think the reason that bi woman seem so prominent is because when the female half is attracted to the female half of a couple and some bi women have to be attracted to both the female half and male half to want to interact with a couple. The couples with bi female will approach a couple and are sometimes agressive because that is the only way the husband is willing to play and maybe that will be the only time the wife will be able to play. I the female half enjoy reading the forum sections on different sites. I have also read threads on women who will start with the female half of a couple for about two to three minutes then turn around and play with the guy half of the other couple until orgasm. These are the straight woman that get with a couple with a bi female who starts with the female just to want to really get with the male half. Then this leaves the woman of the other couple who was truely bi upset. So if your wife does not want to play with bi women, don't let them change her. It will only make people angry and confussed. We have also ran into couples that when they find out that the female half is not bi, they want to move on. We agree with VegasLee. Let them move on.
