Ok. Some of us do! I have no idea, the menstrual cycle is a possibility, I've actually seen a few bi women here and there suggest that. It's not like there are any studies on this so it's just one idea.

I already explained that I have conflicting desires and the nature of my attraction to men is, I guess, capricious. I know you aren't trying to be rude, and I don't perceive you as rude at all, but I have learned to just accept all this for what it is because it doesn't matter in the long run. Yeah it's worth exploring/trying to understand if you have apparently never encountered it before but I've been through these questions and possibilities with myself alone and with other bi women like me in a febfem group so I'm kinda over it all.

I don't consider it all that odd. Even straight women talk about being repulsed (or just grossed out) by men/male anatomy at times.
