I was in a similar situation in my previous relationship with my ex-girlfriend. I am a guy and (obviously) fantisized about having threesomes with another girl and my girlfriend. Even the bare minimum of watching the two of them go at it would have been fine for me. However, like your girlfriend, I didn't really want to have one and take the chance of screwing up what was a long-term relationship. My ex-girlfriend was slightly bi-curious and fantasized about it too, but felt the same way as me. We had casual conversations about the general idea, but found we were on the same page.

While I did bring up the conversation each time (really to test the waters for her), I doubt I would have ever gone through with it even if she would have wanted to. But still, often I would think to myself "if only I wasn't madly in love with this girl I'd be up for it" or even "if only we had maybe had a threesome when we first me before we got too serious."

So to tie this back to your situation.....it is likely she will never really want to act on it, but talking about it as if it is a possibility helps her get off enough to it to make her feel like she is experiencing one without actually having to and roll the dice. On the other hand, maybe she was just testing the waters to see how you felt about it. Maybe she really does want to have one, but didn't know how you felt and just agreed with your point of view to not scare you or whatever.

Either way, it all comes down to how much commitment she has in your relationship. I wouldn't go around worrying about it. If the trust is there, then everything is fine. The fact that you can fantasize about it together will bring you closer really. Perhaps you all can do other stuff (like strip club lap dances) to tease each other with similar things, but obviously avoid true sexual activity with a third person. In the end, communication is key and you probably have nothing to worry about.

I am wondering about that, too. But that's just it, nothing more.

I have to disagree about all women being bi, or having bi fantasies or repressed desires. Nope. Never has a woman come remotely close to doing anything sexual for me. No thoughts, curiosities, nothing. Nada.

To me, women are friends, mothers, daughters, sisters, a lot of things, but not lovers or potential lovers. Not the right 'equipment' to quench the flames.

It's not always about having to have the right equipment. Emotional intimacy can form between anyone, same gender or different. That in turn "can" carry over into physical intimacy in certain circumstances or it can still remain an emotional connection which can be as good if not better than physical sex.

[calamity]

Emotional connections are very good, and necessary - especially between lovers. However, to me, the emotional connections I have with females are not in the same category as the emotional feelings and connections I have with my bf. For me, nothing replaces the physical sex between a man and woman. There's just no substitute. Even if the emotional part isn't fully intact, the physical part is amazing.

I've just never been a big fan of the bisexual label. I'm one of those people that thinks that you meet and fall in love with whoever it will be... whether it's a man or a woman. I've found myself attracted to both, but I'm not sure that I would call myself bisexual. It makes more sense in my head than how I'm wording it
