So, this may just be my hormones raging, I've been hyper sexually-inclined for the past week or so. My bf(26m) and I(25f) have been together for close to two years, we are very serious, we have both had past relationships where our partners cheated and it caused alot of damage. We ourselves are very much monogamous.

Thing is, I have always found women ridiculously attractive. Soft, supple, I want to kiss and touch a woman, explore her body. There is no one in mind, but the fantasy is there and growing. I have never explored this side of myself, other than a single kiss a long time ago with a female bisexual friend. There was drinking involved. Nothing past that though, I was intimidated lol.

But I have this fantasy of having sex next to another couple. I don't want to touch or be touched by the other man, but I want to kiss and caress his woman while our partners have sex with us. And I want to watch the other couple.

I have no idea if I should even suggest this idea to my bf, but I want to. I don't know how to go about it. I would never want to make him feel insecure or that he is not enough. That's why I want him there, participating while I explore a woman for the first time. I also don't want him touching her either, my psyche couldn't handle that.. hence her partner being there to attend to her needs as well.

I guess I'm asking, how do I bring this up? Or if I even should? For the sake of our already wonderful relationship, should I just keep this as a personal fantasy? If I were to go about it, what rules should be discussed, how can I make sure we both remain secure with each other?
