Hi, I am new here. I am a guy and I am 43. I've been in a relationship with my girlfriend, who is 52. We are both straight, and our relationship is perfectly fine, and have been together for a little over 5 years. I am very happy with every aspect of our relationship, and we have a good sex life. To be honest, I am more or less vanilla but open minded, and my girlfriend is more adventurous. However, I have had a fantasy of having a 3 some. My girlfriend has a long time platonic friend of over 20 years who is a lesbian, and they are like sisters and it has always been platonic (I jokingly asked once). I consider my girlfriend's friend to be my friend as well, and she considers me a friend, too. Now, even though she identifies as a lesbian, her friend has had sex with men before, and currently hasn't had sex in 6 years because she is a divorced mom (the "husband" actually being her former wife, and her son was actually from a sperm donor), and she works a lot and just doesn't get out a lot. She even has joked a couple times that maybe she should just break down and have sex with a guy, just because she is that hard up, but I honestly don't know how serious that was. She also lives out of state (MN), and visits here in AZ once a year, usually in the summer. My girlfriend is straight, but says she has kissed a girl before more as a curiosity thing, and is not disgusted by lesbian sex. In fact, she and I have watched lesbian porn together, and she gets turned on. She even said that if she was not enough for me, she would be open to a possible 3-some, but in reality she is all I need. And she has told me she doesn't need a threesome, either, and would only do it for me to make me happy (which makes me feel a little guilty, because I won't ask her to do something she didn't want to do...I care for her and love her. she is my best friend). So my girlfriend being with another woman is just something she would not likely seek out on her own. AND this conversation took place a while ago long before I met her lesbian friend. Anyway, I have had a fantasy for a while, where my girlfriend, her lesbian friend and I all go out drinking, and come back home for a 3 some. I fantasize about me and my girlfriend's lesbian friend double teaming her: taking turns going down on my girlfriend, maybe both of us eating her out at the same time, watching her and my girlfriend have sex, and maybe even fuck her friend, while she eats my girlfriend. Now I am very happy with my girlfriend, and I don't "need" this fantasy. It is just something that if it did happen, it would be awesome. I would never cheat on my girlfriend, either. Also, the idea of posting an ad online to get some other girl for a 3some really doesn't turn me on. It's just the idea of her friend, my girlfriend, and I that appeals to me. And I am not sure why, exactly, because I would never have sex with her friend, unless my girlfriend was there. Also, I have never told my girlfriend about this fantasy. Basically, I am not sure if I should tell her, because I don't want to mess things up between my girlfriend and I. Even though my girlfriend might go for a 3 some, I don't know if she would go for it being her friend. Likewise, I don't know if her friend would go for it, either, even if my girlfriend would. Has anyone been in this exact situation, or know someone who has? Should I just keep this to myself, or what?
