I am a bisexual female in my mid 40's. My husband is 55. We have been married for 17 years and dated (lived together) 3 years before marriage. We are very open in our communication of our desires, fantasies, and needs both inside the bedroom and out. We are very respectful of each others boundaries. We have taken our sex life to very satisfying highs. We are considering entertaining some of our mutual fantasies on a more "involved" level. Starting out by sticking a toe in the water before we jump into deep waters and we both have mutually agreed on boundaries and the willingness to discontinue advancement of engaging in anything that the other is not comfortable. I utterly trust my husband and he confesses the same for me. We do not have fidelity issues. I am not here to solicit in anyway but what I am seeking is the mature experience or wisdom of those who have experience or knowledge in the arena we are discussing. We are entertaining the thought of a menages a trois both MMF & FFM but we are no where near ready to jump into anything headfirst. We enjoy voyeurism and exhibitionism and although we have not actively participated in either we thought that might be a way to dip the toe. We were thinking of actually going out of town or doing something via internet whilst our identities are kept private via masks. It would be in such a way that there would be no other contact with the other parties after the event for we are not introducing someone into our emotional relationship, just sexually. We thought that from there, if we both were still interested, we could move into locating willing parties to participate with us and there are other issues to consider..sexual health, defining boundaries for what would take place between us. We think that remaining as anonymous as reasonable, going somewhere out of town/state, with no further contact with the 3rd party would be the safest way to ensure emotional attachments do not form. We have no hesitation with pulling back if we feel in our relationship would be threatened. Has anyone ever done this? Did you have any issues and what were they? Is there any advice for those who may have had a pleasurable outcome and enjoyed it? What guidelines did you use? I can see completely where entering in a relationship has real dangerous of causing damage. I've read the book A Billion Wicked Thoughts and really have researched a great deal about all aspects of sexuality in the male & female brain. We are very mature. We are completely comfortable with our sexuality and have indulged in the delights of each other and we are just wanting to expand on those now. We both agree that an evening of "fun" isn't worth a lifetime of commitment so we are both anxious and excited to hear what others have to say on the same token we aren't in a hurry to make it happen. Thanks for any advice or insights others may have.
