How many women are Bisexual/curious

I'm a bisexual female my first experience with a girl was when I was in 5th grade me and my best friend used to rub each other and both thought it felt amazing ever since I've always been attracted to females,,I've had a couple girlfriends in middle-high school but never anything serious. Just wondering how many other moms/wives are bi as well? Alot of my friends are weird around me cause they know I like females as well
