I need some help so any advice would be great!!

[i'mjustagirl]

I am a woman and I have a fantasy. I think there would be nothing hotter in this world than to watch a guy I was dating hook up with a gorgeous girl with a beautiful cock. But, I dont know if I can ever tell a guy that I want to do that. I don't even know how to approach that conversation. I just think there comes a point in every relationship where you have to turn it up a notch just so it doesnt get mundane or boring. I just think it's always good to try new things and have an open mind, but I'm afraid I may be the only one with an open mind. Anybody got advice or stories dealing with this sort of thing??
