Biual men, is your uality dynamic or does it change over time?

well ive considered myself gay practically my whole life but have kept my mind open to women. now within the past year i find myself much less attracted to men and more attracted to women. problem is, ive already come out as gay for a little while now (technically bi but at the time i was only really interested in guys). i was so deadset on men though, that now im not interested in them as much im totally obsessing over my uality and its driving me insane!! i know its best to just go with the flow but damnit i wanted to like a man! so.. that leads me to the question, is uality dynamic for most bi guys? and i suppose should i still try to be with guys now that im not nearly as attracted?
