Question: When I fantasize, it's always about women...especially when I am pregnant. Is that normal for an otherwise straight woman?
Answer: What we know about sexual orientation is that there is a continuum. Research shows that many people lie somewhere on a continuum. It sounds like this is just the way you are, and there is probably nothing you can do to stop this. I would just accept this and not worry about it. If you consider yourself straight and have desire and enjoyable sex with your husband/partner, then I would just not let this weigh heavy on your mind. As far as pregnancy, I imagine that you experience this because you have much more estrogen in your body when you are pregnant, so you have more biological libido. So when your libido is higher, your fantasies probably just increase.
