<human>: Can you condense the text into three sentences or less?

Ok /r/relationships, here is my predicament. I've met this girl and things are going fantastic. We've been together for a few weeks. I'm not sure if you could classify us as bf/gf, but thats besides the point. She and I are at a great point, learning everything about each other, very open dialogue for our relationship, etc.

She has revealed to me that in her past, she's dated girls. It stemmed from a somewhat abusive experience with a guy, but to where we are now, its not affected her with me. The thing is, she's brought up being interested with me and another girl at the same time.

Now, like most guys, my reaction at first was *BOIINOINOINOING*, but a problem that I soon realized is, I'm very huge on fidelity. I do NOT believe that a relationship can be full when/if someone cheats. Every relationship is built on a foundation of trust, and no matter WHAT another person says, does, promises, etc...once that trust is broken with cheating, it can never ever go back to where it was before, which is why I will never tolerate cheating in a relationship, first time is last time.

In general though, I'd like to think of myself as a understanding guy, and definitely willing to TRY and explore this side of her, however I'm not sure how to get over my deal with fidelity.

What is some advice to give to work towards that step? She has already said she would never touch or want another guy, and a girl situation would only be when I'm there with them. but what else can I do to help this situation? How can I get over my fidelity issues to enter the ultimate man fantasy lol? ><
<bot>: my gf likes girls and likes threesomes with another girl and me, I have fidelity issues and a no-cheat policy, what do?
