Am I bisexual???

So, throughout the years that I have been dating I have only ever dated men but, in the past year I have had this Burning urge to be with a woman! I currently have a boyfriend and I'm not sure if I should tell him?? Or keep these urges to myself....lol I could think about going down on a sexy woman all day hahah❤👌 it seriously drives me crazy. I am constantly turned on by females. 😍😍
