Hey, I'm new here and new to this lifestyle, and I have a few questions about my situation.
A few months ago I told my girlfriend that I was interested in the swinging lifestyle. She didn't seem to have any interest at the time, and told me that she would never do something like that. But that was that, and I dropped the subject, after joking around and setting a basic rule system. Like, always use protection and ask my permission before hand, that sort of thing. But she still wasn't interested, which was fine by me.
Just last week we went to a party at a hotel and got drunk with a bunch of friends. Both of us were very intoxicated and having alot of fun, eventually every one went back to their rooms and my girlfriend and I had a little "after party" in our hotel room, a quiet way to end the night. A little while later, and a few drinks deeper, I couldn't stay awake any longer, and passed out.
In the morning I was awoken with a start and a sad looking girlfriend with a long face saying "I've done something bad hun" I immediatly knew what she had done, and said it was okay, but asked if she had used protection. And to my surprise she hadn't. I was quite upset. And even though I told her it was okay, I felt as if I had been cheated on. Later, after my hangover subsided, I got curious and started asking her questions and all that. Eventually she told me that basically it was okay for her to see other guys, but not okay for me to see other girls.
Why do I feel hurt?
Why does she think it's okay for her to see other guys and not okay for me to see other women?
Does it sound to any of you that we are ready for this type of thing?

I'd greatly appreciate responses.
