A couple of years ago, I met Julia, and at first we dated and got on like a normal couple. Of course we had sex, and quickly were able to talk about our sexual fantasies. I was very pleased that this was the case as I had previously been in a relationship where my partner wouldn't chat about what she found sexy, whatever I said to persuade her to open up. With Julia, however talking openly it didn't take long for me to admit my bi side, or her to admit that she was still quite young and thought that she wanted to have sex with more men in her life before she settled down forever.
In light of this we came up with the idea of an open relationship, I can't really remember who suggested it first, but we both thought it was a good idea, and that we had a relationship and friendship strong enough to deal with it.
Although I find women attractive, I felt that I was missing sex with a man. I had previously actually led a gay lifestyle, and being completely cut off from that world, made me quite unhappy. I caught up with some gay friends who were surprised and pleased that I wanted to join them going out and partying. When I explained what was happening they were characteristically unsurprised and non-judgemental and introduced me to a couple of guys they knew.
The inevitable happened and after a fun night of drinking too much I ended up going home with a guy and having a good time sucking each others cocks. Even when I had his cock in my mouth, I looked forward to going home and telling Julia what had happened.
When I got home, still quite early I crept in and got into bed with her and quietly told her I had started opening our relationship and had done another man. She turned and smiled and seemed very pleased. She then casually told me that she had fucked four different guys so far and was really into one particular bloke.
I was shocked by this; I had thought that she would have told me when it happened. When I expressed my shock she was slightly annoyed and told me that I wasn't allowed to be angry about it, when we had talked it though before. We settled down for a nap, and she dropped off quickly, but I couldn't stop thinking about her with these other faceless nameless men.
