Thunderbear,

There is such a complex biological response happening during the lovemaking process! Sometimes it can throw us a curve ball, don't worry, it's all normal. Fantasy thoughts during lovemaking are just thoughts. Thoughts don't make you bisexual, homosexual or heterosexual.

Once, a friend confided she fantasized about bestiality during sex. She was a wonderfully kind wife and mother, her fantasies were, well, just fantasies that worked for her.

I've learned to talk to my spouse about my fantasies, even the ones I'm apprehensive about. I have to bring light to them because of my childhood sexual abuse issues. The whole "keeping a secret" thing can get out of whack for me if I keep it in.

I don't recommend acting on the fantasy in real life. That's a fat grenade without a pin, ya know what I mean!?
