"Bi Women" or "Bisexual Women" are becoming more and more common in The Lifestyle. While the popularity of "Bi Men" is also growing, it is growing at a much slower pace and heterosexuals are still the primary type of swingers in The Lifestyle.
Seeing your spouse pleasuring and being pleasured by someone else can be a real eye opener, it can be difficult the first time. I agree that as a couple you should not be looking for something better than what you have in your relationship together but you must prepare yourselves for the reactions that you will see in your spouse/partner from the pleasures of a possible new technique by an added swinging partner. In making love together there are times, depending on your sexual positions that you cannot see the expressions of your spouse. Prepare yourselves for these expressions when seeing him/her with an added partner. One enhancement while swinging that my husband loves is that he has the opportunity to see me fully in positions with others, allowing him to see ALL of my expressions that maybe he has missed when he and I are alone making love together. Do not expect to be totally comfortable the first time but if swinnging is for you, you will continue to look toward your next experience.
A polyamorous couple is a couple who adds others to their lives for not only recreational sex. There is more of an emotional attachment/love between all involved. Although there are many polyamorous swingers, practicing in polyamory one should be aware of the different guidelines that may not apply to basic swinging.
