I'm not exactly sure how to answer that question for you, but I have a similar problem. I would love to date another girl, but I also would want a guy. In my current relationship, I'm in a three-way with a girl and a guy. It may sound weird, but I don't mind it. I get my straight-up fix from my boyfriend, and when I want my lesbian fix, I can go to her and do it up. When I'm with them both at the same time, I feel like I can't decide on anything. I'm so confused when I see both of them at the same time, but with one of them, I'm more dominant than anyone could imagine.
